Hmm i think most of the Sch Tint is running through are just casual players... in my fc are people who said sch is the easiest healer to play... what makes me angry, they think they can rely on their faery and everything is going well... i play sch and whm myself - whm for main healing and sch for off healing, playing as off heal i often grp up with an ast from my fc - and it works great, really, really great (Team Khalessi ftw yay). I can focus on dots and shadowflare but never lose sight of heavy impact incoming... for me sch (and asts) are way more complex/interessting cls than whms – if you try to be your best. Schs instant heals and mana management just fits great for off heal support imo, while asts and whms toolkits are great for heavy heals.
neverless there are a few really great asts and schs out there who can at least soloheal just as perfect as whms and for me, personally, they should earn much more respect than those common "dps-wanna-be-haha-you-havent-clear-savage?" ones, who often forget that they are still healers in the end... but thats just me... currently im training day for day just to compete with them... :3
in a nutshell: good soloheal schs are still unique.
