Still a bit torn between starting at 3/3 or 2/4. The first option will give me improved critical and then two quick ASI's/feats. The latter stats me off with an ASI, but puts me too close to level 5 warlock to ignore thirsting blade, meaning I'll go 2/5 before bumping champion again.
It'll depend on how you rule on levelling a MC character, do you require a RP reason for each level choice or just the start?
