I didn't get to take a good look at the endgame equip, but the way everything was mods and there seemed to be a big variety in mod traits was a little alarming, yes.It felt too bullet-spongey to me and I hate the bullet-sponge mechanic. Looking at the gear and skills, it reminded me too much of Division 1's grinding RNGs for an extra +0.5% crit.
As for the enemies, it seems to me a lot of them look like bullet sponge until you find out what their weaknesses are. For example, in the invasion mission, the robot enemies were very tough; but each had several weak spots; and all would drop if you could find and stop their controller.
Also, did you play alone? I feel it's a big difference, since even in a two-player coordinated team it's much easier to maneuver the enemy for their weak spots...
Given how the characters dropping out of the random generators look, and given that clothing is mostly unlocked in-game, I wouldn't put much hope in the character creator.The thing I was most interested in was the character creator, which is apparently not in the beta. Oh, well.
Was it too much to hope for that they would have just imported the character customization from Wildlands? Because that was well made.
