Most negative comments seem to come from people who've gave up during 1-50 leveling. I agree with some concerns, bash grind being way faster than questing is stupid, some quests bug a lot if you're leveling in a crowded area and grouping is a bit clunky. I also agree about some other concerns (inventory, bank space, character animations, etc). I myself still have strong concerns about the game's future and Zenimax' reactivity at fixing / improving critical stuff (people getting bank or skill points robbed, main quests bugged since 10 days, etc). I pretty much think if there are no solid improvements / fixes / balance for June, the MMO crowd will jump to Wildstar and let this ship sink.
But when I read complaints about ESO healing I can't but think of people running around, jumping and shit, spamming Healing Springs / Mutagen like rabid squirrels and call it "retarded", "it's nothing but spam etc". These people must be very bad at videogames if they think they would main heal anything in serious content with a ~80 health HoT, especially when any tank will have +3k health. As Rescorla said, while HS / Mutagen can be spammed like Hell until your magicka goes poof, the other spells will be required to even remotely be called "healer". Templar got an area heal ? Yes it's point blank 10 meters and it has casting time, meaning you have to actually know your stuff. Resto Staff got Area HoT ? Yes, it's over as soon as people go out of the AoE, so you can't really spam it while stuff is moving. Most healing spells are designed like this, they come with a downside.
It would be so funny to see those people heal if ESO had hard target healing, where anyone going between you and your target will fuck up everything "omg Jack got healed while I tried to heal Steven omg fuck shit fuck". ESO healing isn't stellar and require a lot less timing / skill / theorycraft than some MMO out there, but calling it retarded because some heals have auto target is just dumb.
