Is this a gladiator who is worth it in the (quite) long haul?
I believe my gladiator's stats are quite ok:
Str: 77 Int: 67
Agi: 82 Sta: 75
Siz: 62 Pres: 54
Chi: 57

Im currently putting all skill points in my Polearms skill, but 'till which lvl should I train this skill before training other skills?
Also, should I save my money to upgrade stuff like Armory and get a barracks upgrade, or should I keep on investing in new items?
I'm just 4 days into this game, so I'm not certain how-to-play on some aspects.
Gladiator is just lvl 3 btw (2-0) (Currently got a 47-80 Polearm, so Im ok with that for a while)

Thanks in advance!
