Amusingly enough, it was not long after I got back into D&D, when I was invited to play in my older brother's 3.5 Eberron campaign, when I began thinking of 'optimizing' my characters. I knew I wanted to play one of the new races, and thought I'd be crazy not to play a Warforged Barbarian. I mean, come on, they don't get fatigued after raging because they're immune to fatigue! How crazy is
that?
From there, I created a Changeling Monk/Warshaper, and I started getting closer to real char-op. I started looking at the WotC forums for help building my characters up, mainly looking for ideal feat progressions and items and such... Then someone linked over to the BG forums, advertising a Play by Post game going on. I joined up and haven't looked back.
Hmm, that was... about 5 years ago? For what it's worth, that game was Sinfire Titan's Skies of Arcadia game, and I was just pleased as punch to be allowed to play a gestalt Ranger//Swordsage with not just the Wildshape ACF, but swapping that out for the Shapeshift variant.
Guess I still haven't really learned my lesson, I still love shapeshifting-style classes.
