Alt-o-clock!

So I've bought some Heirloom gear and been working on my getting my highest level alt to somewhere near respectability lately.

The difference in levelling speed is ridiculous.

Now, I haven't been levelling by using the LFD tool - I'm a little leery of trying to do so at this point - but as I get going I just might start doing so.

But Alrom is my level 69 Paladin (at least for today!) and I've been coming up as a Retribution spec.  Fairly soon, though, I'll be faced with a decision...

What do I want to do in the end game, with my first alt?

Do I want to stick with the Tank and Heals method of my main?  Or do I want to have a DPS or PvP spec to play with?

So I pose this question to any readers that wind their way over here.  What do you do with your alts?  Do you try different roles, do you play the PvP or PvE game that you don't on your main?  Or do you stick with your favorites and play the same game?

Personally I suspect I'll keep Ret as my main spec and Prot or Holy as off.  But that's just me and it's a little selfish reasons why - I like tanking and healing and I also like short LFD queue times...
