Uggh, building a pure meleer in a game thats going to go high level ....
I suppose I can try to be the bigger man. No one wins a pissing contest with a GM in game. The more I think on it the more I like it, give him an Achilles heel, hamartia. That godawful flaw that penalises your Ref save and a low Dex. Don't take Vecna-Blooded and I will a sitting duck but maybe it'll make some good fluff. A warrior haunted by an inescapable impending demise. Has promise.
Since a well-built caster will clean my clock without mindblank of Vecna-blooded protecting me I may as well optimise for fun, the ideas you guys had are way to fun not to try
Something like a Primal Half-Giant Crusader 1/ Wilder 4/ Crusader 2/ Slayer 10/ Crusader 4
A ML of 13 (17 with Practised Manifester), 6th powers known, IL of 12 which gives me a 5 lvl manuevers. Decently good early on, and starts petering out fast past 7th level - but sets up for the impending doom. Lots of options which I like a lot.
Obviously this can be improved on, maybe Ardent and Anarchic Initiate as Phaedrus suggested.
