Its not a bad thing, nor a good thing. Just preference.
If you smoke regularly, and have used that piece a lot in those two years..you're going to have a bowling ball of resin..maybe not that much.
If the weed you were smoking wasn't all that great, the resin will be a higher high. But if you're smoking great stuff, the resin is just a different high. I know some people who swear they get higher on resin compared to great weed, but I wouldn't agree.
Its all different.
