As a since launch merc healer i've seen many iterations of builds come about
one of the things i love about the current system is i can choose to spend my points lower down the skills tree if i choose to, for example i could have three tier 1 skills, 4 tier 2 skills and 2 tier 3 skills. The new system seems to make us choose to have specific either or items on tiers, rather than giving us the ability to select how we want out builds to play.
The majority of players will want the max tier 3, i do feel its nice to have the option to select say two of a level if i chose to rather than my top abilitiy options. It also allows us to fill other roles needed in groups potentially.
I'd love to see the option to have points to spend again and having requirements to get to tiers like in the current system, the layout of the new system im fine with, but i'd rather have more choice for abilities if i want to spend my spec points there.......
