So after doing a bunch of daily challenges with a group, I have some observations.
1) Green daily dungeons are super quick, easy to solo, and don't give much XP.
2) Red daily dungeons are amazing XP when paired with potions.
3) The group daily dungeons are a waste of time. Well, it was for us. We did it (and it took 20-30 minutes) and gained VERY little XP. I'm thinking they get better? I hope?
4) Heal when injured, Heal when damaged as a double affix is fucking stupid. We did the red Taskmaster daily. It was stupidly difficult.
5) While I play Rocket Raccoon, I felt TERRIBLE for the Hulk in our group. Melee gets the shaft BIG TIME on bosses.
6) Drops? Yeah right. I've got 20 hours in, level 29, with NO drops worth talking about. I've ran a bunch of dailies (and maybe 4 or 5 with rarity drop bonus potions up to 75% bonus) and have seen complete and utter crap. Pretty disappointing.
7) Chat operations are annoying. If you reply to a message without replying, you get [Tell Tell personX]. That's stupid. Also, the lack of supergroups STILL pisses me off. It's very difficult to get a group together. Having a guild of people would make this SO much easier.
8) Med packs NEED to come in a higher tier. With ~3000 health, the standard pack is worthless.
9) Speaking of things that need to come in larger options...Money. Money is scarce, and with the cost of crafting higher level items, it's going to get REAL tight.
10) Fucking make crafting mats stack. That's just absolutely fucking ridiculous.
11) Action bars are a mess. 5 options + health pack + RMB hotkeys sounds like a lot, but it's not. Not when you have a character with a bunch of utility skills that are worth using. I don't know how to fix this, but it needs to be addressed.
12) Bosses need to have some sort of indicator above their head. With all the crazy effects going on, it's a mess when trying to target him/her.
13) Speaking of effects, I've lowered my graphics options in hopes to turn off crazy screen shaking and insane blaze and explosions. It just gets to be too hard to see what's going on...Even still, I can't seem to get these things to go down and make my screen less annoying to look at during a large group event.
14) Lag is still really bad in the tower by the crafter. I noticed they added another crafter to Avenger's Tower. Great, but it's still laggy.
OK, I think that's about all I have right now. I'm still loving the game, and I plan to continue enjoying every moment I can with it. But these are things that I really found annoying tonight during my session.
