any other MP games that expanded their loot pool as much as MEA?

I find those games really hard to compare to ME's style of loot.

To clarify I am looking for something like:

In July 2017 MEA MP increased its loot pool by X% all at once.

In XXX year (other game) increased its loot pool by Y% all at once.

I'm aware that Borderlands, Diablo, etc. have effectively infinite loot variations. So I guess I am more interested in 'traditional' loot pool games.

It is quite similar to a new raid tier in an MMO actually. As the game evolves complete huge batches of stronger items are added along with higher difficulty content where the new items help you progress. Its nothing new or special really.

I was just told by my COD buds that the killing floor, a FUCKING FREE GAME WITH ONLY COSMETIC LOOT, just got 6 new maps and a bunch of new characters.

What the fucking, fuck?

Yeah, but those are measurably different with different looks/graphics and objectively better buffs or stats and depending on the game, give a different feel of sorts.

1.09 barely qualifies as new gear outside of a few colors and some new bs mechanic - same graphic, same exact fire type, same rarity.  You can hardly quantify the new weapons as "new."  Oxford would probably even challenge the use of the word.

To OPs nicely avoided, soon to be proven point, this is about as low on the totem pole as you get in terms of passing something off as new content.

This isn't about 'passing something off as new content' which is why I said I wanted to avoid re-hashing the old arguments.

This is about quantity pure and simple.

I don't play MMOs so I don't know: maybe every time World of Warcraft does an expansion there are 1,000 new swords with pandas on them plus 500 new sexy elf costumes on them and this is X% of the total loot at time time.

I am genuinely curious if the loot pool expansion in MEA was really as unprecedented as people seem to think or if it's business as usual nowadays.

It is not just on a new expansion. Each expansion has a number of different raid tiers. Each time a new tier is released all your old items are completely obsolete and you start from scratch.

Don't think MMOs are the correct comparison either. Expansion and raid tiers are prettymuch expected and items from a tier are in a separate loot pool from everything previous.

Let me ask this question another way.

When other loot-based games like (whatever analogy you want) drop a bunch of new (or 'new') loot at once, do people get as salty as they did about MEAMP?

The only other online game I played for any real length was STO. They, all at once, increased the level of all items from 12 to 14 and added a sixth rarity(epic). Each ship has 22 or 23 eq slots and your character has 10 pieces of ground eq. They locked loot drops to MK 12 items only. MK 13 and 14 as well as epic quality was only achievable through their ridiculously designed crafting and update system. Needless to say, their player base was pretty salty. But they get pretty salty over there for a lot of reasons.  

Diablo 3 essentially contracted the loot pool when it released the expansion by changing loot drops to mainly drop items you could use. Previously players had to sell items in the item store and buy items they wanted to and from other players.

I've played a few MMOs and it depends on the model. In SWTOR, major patches and expansions meant that previously BiS gear was no longer so, which was often accompanied by comprehensive crafting overhauls. This was offset by the fact that these changes almost always came bundled with actual content, new things for people to do, new abilities, areas and so on. New layers were added on top of already existing loot tables which was needed to clear the new content in higher difficulties, especially when the level cap was raised. There was no loot pool dilution because new stuff didn't compete with the old in the same loot table. That being said, they did come up with other ways to hamstring players, and righteous rage flooded the forums anyway.

The other MMO I put a lot of hours into was DDO and the model was different, adventure modules were released that added new loot, but rarely rendered the stuff you had obsolete. It was generally different and distinct and introduced new mechanics, spells or characters which increased variety and kept things interesting, something that was facilitated in part by a mix of randomly generated items and named pieces.

Can't speak for anyone else, but what pisses me off is that, barring the batarian and Kishock, none of the shit they added in 1.09 is new. You have reskins, you have flat numeric modifiers. Snap Freeze is basically Cryo Beam on steroids. The concussive guns barely count as new mechanics, they simply cause AOE damage on a headshot kill... whoop-de-fucking-do. At the same time, all that fluff also makes it harder for you to get the stuff you want. Again, compare it with the ME3MP DLCs. If the thousands of new cards added were in fact for new I-X guns and characters, the reaction would be completely different.
