My biggest concern with Dominion (and probably one of Riot's biggest concerns..) has got to be the challenge of balancing the champions on both game types. There are 2 ways of approaching balance of a single champion across more than one game type:
1) Leave the champion unchanged across all types but balance the champion such that its power level is at a reasonable level on all types.
For example, the attributes that seem to be of utmost importance in Dominion are:
A) Small scale fighting abilities (1v1 & 2v2)
C) Global ulti's like TF, Pantheon, and Shen will be very very strong. They allow an unpresedented amount of mobility.
D) Map control skills like teemos mushrooms or nidalee's traps will be incredibly useful as wards are disabled.
In summoners Rift, the most important attributes are:
1) 5v5 team fighting abilities
2) Lane sustain
3) Turret pushing power
The problem with point #1 is that it makes it incredibly difficult to balance the game. For example, look at Nidalee. She's very strong at pushing, small scale battles (1v1 & 2v2), lane sustain, and mobility. Although she lacks seriously in team fights, making her reasonably balanced on SR. This set of attributes works mostly fine on SR, but would be insanely OP on Dominion, as she has very high levels of the most important attributes.
2) Create a seperate version of each champion for both game types by adjusting base stats, skill power's/durations, and AP ratio's.
Many players would not like this solution and it would be confusing to new players (your champion is suddenly healing for 1/2 as much on a diffrent game type.. or is running significantly slower and doing more dmg, etc.)
I imagine this has been discussed quite a bit at Riot. What's the consensus? Do you find that these points are an issue from lots of play testing on Dominion?
What do you guys think? Is it even possible to balance both types (without making 2 versions of every champ) and have a reasonable amount of balance for it to be enjoyable? It's incredibly difficult to balance 60++ champions (with more being added every month) on a single game type, adding a second one sound's overwhelming. Will Riot simply balance for SR and just ignore Dominion? (like they do with TT currently..)
