Background : very new to the game (3 weeks so far), but not the D&D ruleset. Right now I'm messing about with most of the classes to try and settle in on a main. I've done Rouge up to about 9 and like it, and now want to play my Pally a bit more as I've always preferred to play tanks in MMOs. I've decided I want to drop in 2 levels of Fighter for some feats, and while I've seen loads of info on different builds I haven't seen anything which says when you should take your first multi-class levels (other than take any Rogue levels at 1 for the extra skills).
I forget the name of the spec lines, but I'm going sword and board and only occasionally whipping out a 2hander, trying to make a tank build, not a DPS one. So I'm wondering if there's a sweet spot for when it's best to take a few fighter levels? Like 'taking them before 10 makes future content a lot easier in the end', or 'don't bother until you hit 18', or what have you. Since I don't have a lot of time invested (only level 6 now) I'm not opposed to killing it off and rerolling either now, or down the road if it looks like I messed something up. But I would like to know what the general consensus is for taking a level or 2 of Fighter.
