Spring attack requires dodge and mobility. I like spring attack. Have it on my fighter and it is very useful hitting stuff while dancing around the target. It helps me reduce the amount of damage I take because I can move while swinging and not worry about any penalty to hit.
I'm also a twitchy player, at least I try to. It is wierd in the game because the range at which you get hit is quite a long away. I've been hit by melee that should not be able to hit me from the distance it was standing.
I rolled my rogue but went with a higher STR. Can't quite rember the rest of the stat distrubution. Taking fighter earliear and will take a few other feats sooner and move others to a bit later.
I do know that I left my DEX at 15, CHA at 8. My CON scores are always high because I like a lot of hitpoints. To be able to make sure I'll have a good UMD, I'll shift some spare gear(Planer Gird, yes I scored a few of those,) look for other UMD gear, and make sure I have a good CHA item.
I may be able to gear this character into an AC character when it is needed. I'm not sure on the Intim part but I may be able to get that high enough. I do have other pieces of gear that will help get my AC high but it requires a UMD that my fighter doesn't have yet, but since I should be able to get my UMD up fairly high, I might be able to AC/Intim when such a character is needed, but that remains to be seen still and is just something I'm thinking about.
I'm not focused on AC. My character is DPS with rogue skills. It is nice to be able to put on the gear and Intimtank critters such as in VoD if I can the right gear and make my Intim high enough, but I'll see how things are when I get to that level.
