some unfiltered thoughts on current healing balancing:
heals are boring, brain afk spamming raid heals and HoTs
i remember times when heals actually had to make quick decisions on who to heal when and have good time management and positioning. this is all gone now and you only spam anything not caring who gets dmg.
one exmaple for this is when i am playing tank, i usually was able to regenerate mana by regularly using holy power explosion and being directly healed, now i am mainly healed just by HoTs missing out on this manareg.
another one is that having life-draining buffs up all the time does not make any difference, blood arrow from scout main and sec classes, holy candle from priests, or m/r gift of the baron(which on top is a strong raid-hot itself) and ch/wl elites do not mean any disadvantages anymore as long as heals are around, their life-drain just vanishes under all those hots.
this is mainly due to these changes:
healing skills and especially hots are scaling too much with wisdom, having 150k wis is enough to heal anyone to max. health each second, having 200k+ wis is just ridiculous amounts of healing, pls consider reducing the scaling.
we now have many heal combinations with viable healing skills and HoTs that affect the entire raid at once, making targeted healing obsolete as well as many, many more skills reducing dmg taken for the entire raid, preventing in certain situations that the raid takes dmg more than hots heal anyway.
also the class balancing brought us some raid-buffs that increase the healing taken, buffs like priests blessed pring water and k/d potent blessing make healing even more of a joke.
on top of that we have many more aoe-cc skills from tanks and dps-classes, which reduce the incoming dmg even more.
having alts follow you with makros that keep up hots and spam raid-heals is practicly as effective as having a human healer.
this fact is demotivating AF.
nowadays tanks rarely have more than 2kk hp and almost no dps has more than 1kk hp, you can heal them with 1kk+ urgent heals twice each second atm. this is simply too much.
and using urgent heal is not even necessary while having 4 ore more hots on the entire raid, 2 of them heal 2% each tick + ~100k and 2 of them heal 250k+ each tick.
at the moment using short-term buffs like healing slave/healing seed or bufffood like garlic bread or spicy kale chips or even any casting speed increasind buffs/food is just obsolete, because there are no situations where heals do not heal more than enough already.
another way to balance this issue would of course be heavily increasing the incoming dmg for raids. before the class balancing you regularly had to pause for a moment to heal the 50% dot those mantis in rofl have, now we just do not care anymore, simply charging forward into the next mobs while keeping up our hots and maybe blindly spamming mother earths fountain.
dots from other mobs in rofl are not even worth to mention, they just vanish the same way as the buffs i meantioned above.
i would make a list of skills that could need some changes, however this would practicly be all healing skills and combinations, which seem to be quite well balanced one ot another, however this might be hard to really evaluate while all of them heal way too much.
so reducing the healing amount in general would be the easier and more useful approach i guess.
please consider this, to give us heals at least some challenge in this game.
other classes have to make some effort too to be effective, why shouldnt healers.
Cheers!
