Warband personalisation

I'm new to warband-skirmish tabletop (it's been like 15y since I ogled some obscure rules for LotR warband gameplay, never got into it) and since I like modifying models but ain't too experienced, I'm wondering how much you'll miss out on strategy-wise if you just go by the official miniature designs. Like, even only the possibilities of Homunculus modding seem quite overwhelming, I'm borderline relieved that I'll 'only' play Pilgrims. So, just going from what minis have been released so far and what you may have experienced in games, do you think kitbashing and converting is necessary in order to get the full strategic range of a faction?
