you should edit out that points cost...
I like your build here. I think that 4+ Ward is really solid.
Here's my build (to negate such ward save-age):
Scar Vet
Light Armor
Shield
Cold One
Piranha Blade
The other tricksters shard
Battle Standard Bearer - no reason not to! Re-roll stupid tests etc. +1 to combat res. and in the new rules he can still use his shield! (right?)
It's more aggressibe, but also more well rounded. 1+ armor save. Only one wound has to get through, and ward saves are made A lot worse. I think the other tricksters shard is gonna be a great item in this battle...
Why not put him on a mount though?
lots of extra points to throw around.
The only mount would be a cold one (unless you sacrifice a bunch of gear to get a horned one which defeats the purpose of tooling out a scar vet), and throwing stupidity into the mix isn't a good idea.
A ld 8 cold blooded SV RARELY fails a stupidity test. and even if it does...so what? it moves d6" forwards, doesnt lose any attacks, and we'd be striking last anyway or getting charged anyway without the cold one, so whats the diff?
The diff is this: an extra s4 attack, + barded mount armor save (thick skinned), and FEAR. If they don't pass that Fear test...they are hooped!
