Besides the usual and expected bug fixes, these are the top priorities I'd like to see Relic focus on for the next patch:
1) Balance - Should be equally based on the massive amounts of data acquired by that point, as well as the constructive feedback from seasoned players.
2) Skull Accumulation - Too much of a grind at this point; this isn't Diablo 3 and MP is the main reason most of us bought this game.
3) Concede Option - This is ruining the fun in a significant way; time is a virtue that not everyone has an abundance of (this ties into #2)
4) Replay system - Needs to be revamped and we should be able to view earlier version replays. This game obviously has a huge learning curve and IMO there's no better way to improve your skills than watching how seasoned players micro/macro/strategize and rewatching your own games to see where your holes are.
Should not be priorities at this point:
- new maps
- new game modes
- next DLC content
I'm genuinely enjoying the game in it's current, unpolished state. My biggest fear is that the developers are under-resourced, especially in regards to properly balancing all the new highly complex variables impilemented in this iteration with elites and doctrines.
