I know your suggestions are towards for adoramus AB's but:
In terms of the healers circle, I feel it is very silly that this one pivotal support class is mostly still relying back onto its first class skill tree comparative to other classes that advanced mostly to use it less from it or to not even use them period. I am it is understandable that I still need to use skills like Heal and Blessing and other such things for single targets and I see nothing wrong with Ressurection, I am more aiming at how our healing capabilities are mostly based off how much we heal using 'Heal' instead of getting a better off formula or better yet, a completely newer formula. I mean Renovatio is sort of nice, but mostly its garbage compared to what it could have been (RO2 is a finer example, OP but acceptable). with essentially the majority of items being a spammable option, Healers are more of a sub-category to gamers than actually being part of extremely strategic parties, there should be at least a bigger major role for healing in todays contemporary gameplay.
But of course i still welcome the future of solo gameplay thats incoming, progression is just that way, but im just speaking this in terms of extra variety.
