it was a broken combo that trivialized any hard encounter.
Unfortunately, the standard can be cheesed a lot. I've seen it produce just ridiculous levels of surgeless healing - especially when two standards are dropped. It was vomit-level of over-effective and I wasn't even judging the table. I actually had my PC not count the second standard because it was so broken in this super-healer's hands. It wasn't a cool move and a hard decision; it was a broken combo that trivialized any hard encounter.
