Though it is annoying, having to re-level my exotics isn't too big of a deal for me. The real problem is that if the current trend continues, I will have to do exactly the same thing all over again in a few months when house of wolves comes out. There's really not much point bothering to level up exotics cause I know they're just gonna be reset when I get the next DLC (Which I will be cause I got the season pass). That's the real problem with exotics resetting, it makes the act of upgrading them completely pointless to begin with.
