Honestly, I have a good jpn friend that is a 71whm, and he said not to bother with erase unless you can get it from the bcnm fight. It's one of those things that you can certainly live without, and while it is a convenience once you have it, it's by no means necessary. As he pointed out, think of all the other things you could do with that cash in the meantime that will have amuch greater impact; don't blow it on a spell with minimal utility (at best). And, btw, haste DOES overwrite slow, which is really the only nasty debuff you have to worry about until later on anyway.
