What is your progression plan?

Just buying the 100k packs, have done that since the first day pretty much. Maxed my Commons by buying Basic packs not long ago but that was a chore. I just end up saving 100k+ credits anyway, why would I not buy the expensive ones? My Rare toys are at higher levels than my Uncommon ones, but I guess I can live with that for now. The goad is the Ultra-Rare stuff and while they are indeed rare as hell, overall I can't complain about my progress thus far in this 1-week old game.

I'm lucky that the my favorite class is a Common so it makes my progression a lot less infuriating.

Like a lot of people suggested, bought a bunch of Basic Packs until I got my favorite kit to X. My Common weapons maxed out at around the same time with some useful Common mods up to halfway. At this point I can go into Silver pretty comfortably; Gold is a challenge for me still but it's doable. Skipping straight to the Premium Packs now and crossing my fingers!

tl;dr Max out kit and common weaps, farm credits, check for the weapons that I want and open the relevant Packs.

Buy 5K boxes untill maxed commons
Buy 20K boxes untill maxed uncommons (I am here, roughly 40% done I think)
Buy 50K boxes untill max rares (I am here)

Only thing that will change this for me, is if they release an UR character or weapon (like a kinetic high ROF rifle like the Harrier , or a character with an interesting power setup) that I MUST HAVE RIGHT NAOW!!!!

Otherwise it's fairly smooth sailing.

I am very interested in step 3. Tell me more

Finish SP, then play Bronze. Then see what happens. If I enjoy it, continue. If not, go back to SP replay.

I'm working on common/uncommon, not in much of a rush, tried Silver a few times but just got wrecked in wave 3 or 4 so sticking to bronze until I get some better gear..
At the moment I get about 150k in an evening so tend to get 5 20k boxes and 1 50k one.
For Rare items ive only gotten characters, no weapons..

I maxed my commons by basic packs. Then i went for the uncommon items via the advance packs - but i just need weapon attachments in an effort to make something else then my Vanquisher and Equalizer fire more then a wet noodles....

So for every 5 advance packs i buy one golden in hopes of getting something worth a damn. So far i havent - but i did get ultra rare from one of them...

Somewhat relevant; where's the item rarity list?

Best plan:

Wait until Bioware fixes this mess with patches and DLCs, and once the game is actually playable and we have good weapons and characters, start having fun.

Play other games in the meantime.I am not kidding

Played 32 hours so far. The plan is to try to complete the gold/rares within the first month.

So far I completed the bronze unlocks on monday afternoon and i've almost finished the silver unlocks this Thursday in about three evenings - just six more silver weapon upgrades to go (carnifex VII, disciple VII outstanding).

1. So far in terms of strategy nothing fancy, pugging like mad, moved to silver as soon as I had a level 10 character and opened nothing but basic packs to complete the bronze set.
2. Next I took my level 20s to gold, stuck to outlaws and opened nothing but advanced packs to just about complete the silver set.

Now I can just about start thinking about the rare/gold tier.

I think for the next 10 games I'm going to stick with advanced packs just to see what the rare drop rate is like from these packs after removing all the un-commons from the pool/equation just to gauge a rare drop rate baseline comparison to compare with expert packs. With a bit of luck i'm hoping this will be by far the cheapest & quickest way of maxing out the rares.

After completing the rare / gold tier and removing all the rare cards from the pool I've got no idea whether premium or expert packs would have higher ur drop rates but it's going to be fun finding out by the time platinum rolls around.

I have two level 20 soldiers. Levelled the first with the charger. It sucked*. Levelled the second with a raptor. That was much better. Got all commons to x in no time while in bronze. Levelling my second vanguard now. Using the talon.

* it sucked on anything other than bronze anyway. If you mean it's great on bronze then, yep, I agree.

I've got all my commons unlocked, and am currently working on my uncommons. Also working on leveling any unlocked characters that have power recharge as a bonus to 20. It's gonna be a lot of silver games before I see any significant progress.
