Two weeks of Dragon Soul runs since returning to WoW after a two month Skyrim/whatever break and I manage to snag 5/5 pieces of Tier 13. Nice. This almost makes up for 6 years of bad rolls. Also, if you were in that one run with me where I broke the one item per run rule and won two of the armor tokens, I'm sorry :(, trigger happy.
I like the raid finder; It's simple to use and gets people who wouldn't normally have the opportunity to raid (or like myself, don't have the time to participate in a regular schedule and don't want to sit in LFG all night), into the new content with minimal hassle and server drama.
