I started playing back during TBC and leveled a druid, but took time off till the middle of WotLK (and then leveled them again to 80). I raideded, but only rarely as dps. Seemed like anytime my guild was getting a group together all the melee dps spots were already conveniently filled and when raiding PUGs really caught momentum on my server it was the same deal. If I mentioned tanking then I was pulled into the group so fast that you'd think Blizzard themselves had come down off the mountain and made it so. I did well dps-ing on my druid when I had the opportunity, regularly scoring in the top three or top five of 25-mans in LK, but in spite of this the 'tank or nothing stigma' persisted.
Cata gets released and I leveled my druid through Cata content and got him to [mostly] 346 gear. Start doing my daily heroic but by this time I was just kind of worn out playing as a druid.
So I start leveling a rogue that had been sitting at level 12 since forever so I can experience all the new content. I found myself liking it so much that I took him all the way to level cap and started the grind towards (hopefully/eventually) raiding. Feral druid and rogues are similar, but certainly not the same and I found the play style refreshing and I like their abilities to easily control mobs for whatever group I am in.
As a result, my druid has been sitting collecting dust and gets a single heroic in about once a week.
I was telling a couple IRL friends who are in the same guild as me about how much I enjoyed playing as a rogue and was pretty much told that I am better off sticking with my druid since I have a better chance to get a slot to raid as tank (or offtank should a tank go down) and that rogues spots are rare in progression raiding.
So for those who are already raiding in Cata as pure dps, do you find it hard to get a raid spot?
