Okay, I was wrong. It became a full rework in the end :D
It was just too hard to juggle all the balls with just talent changes, and initially I just taught that a few talent changes at the right spots would help (and spent ages fiddling with just 3-4 talent changes). Yes, they would, but there would still be no clear design path, nor would it fix the design issues around talents that just affect a single of her openers have (namely the disproportionate reduction of value for Valeera's other openers).
This choice forced me to scrap her Opener talents, either by making them baseline (Death from Above), baseline at reduced value (Assassinate) or removing them completely (Blind) or adjusted them so they affect all openers (Hemorrhage), or the latter but utilizing the poison functionality (Strangle).
Then completely restructured her Talent Tree, as I got the idea that every tier should have one of these three options:
- Damage. (Needs no explanation.)
- Offensive Utility. (status effects, mobility)
- Defensive Utility (waveclear, survivability for you and your teammates.)
Yes, this includes her ultimates.
I don't know if it's a good idea - you are the judge - but it was a very clear design goal to build towards, so it didn't actually take as much time as you would expect for such a massive list of changes.
I am also sure that not all my ideas are unique; some of them are shamelessly borrowed from elsewhere but fit right in with where I was going.
