"facts" that were believed to be self evident (by ME3 veterans): so, what do we actually know ?

has any of following points been tested or confirmed yet?     (please feel free to add more - I am sure I am missing many)

1.) "A 6/6 power combo does more damage and has a greater radius than lower tiers"
1.a) "an elemental ammo primer counts as a level 1 primer"
2.) "Combos scale into higher difficulties"
3.) "Powers don't scale"
4.) "To increase "power damage" does not increase combo damage"
5.) "things that detonate later benefit from cloaking bonuses if the player is cloaked the moment they go off and not the moment they are thrown"
6.) "enemies will continue to spawn on gold until the wave budget has been depleted, making it more effective to kill the easy targets quickly and over and over before moving on to the bosses"
so this I can already confirm to be wrong in Andromeda.  At least for bosses like the Hydra.  Which is actually pretty cool, because it makes it a viable tactic to take out high value targets first. nice. 
7.) "random/random missions give more XP and credits of course"
haha... nope
8.) "the shield gate cannot be broken by conventional ammo on gold"
seems to be wrong, too.  sometimes I kill shielded enemies with a single headshot.
9.) "the cobra can save your ass in emergency situations"
In Andromeda the Cobra is actually the thing that puts you in danger in the first place. And in case you managed to get it out and are still alive it will disappear again if you breathe before using it.
and in those very rare cases you are still alive it will then tickle the enemies instead of killing them, making them REALLY angry
10.) "bonuses like 15% more weapon damage or cyclonic shields from your consumables / gear / character trees are applied on the BASE value BEFORE all other evolutions and powers and mods are applied".   
(only vary rare bonuses are multiplicative - and I yet to see one of these typical ones here)
11.) "armor means:   the enemy's armor mitigates a bullet damage of 50.  So if your weapon has a bullet/pellet damage of 80,  30 will go through.  "armor weakening %"  is applied on the 50 damage that would have been mitigated"
12.) "on certain armored targets you can get "multiple hits" in case your penetration goes deep enough  "
13.) "penetration mods stack"
