Give pure rogues weapon finesse for free at 5

[Renouncer]

I never realised how feat starved a pure melee rogue really is! Weapon finesse has always felt like a feat tax to me.

Pure rogues are perhaps the strongest class in the game.  Im not sure they need to get any stronger.

Perhaps they could get it as a minor perk option, the choice to give up a minor perk for weapon finesse seems fair enough.
