It seems too much for what it is. As it is, it’s like you took squire (already very good) and souped it up, reducing the time and adding better traits. Fewer skill points, though. Oddly few considering how many skills you have there. Most LPs have around the same number of skill points as skills.
First, I don’t think +1 M,P fits. And combined with the short (4 year) duration, it’s a very powerful path for getting very high starting stats. I’d put it at +1P. If you really want to emphasize that they improve their minds (how exactly do you see that fitting in your setting?) then make it +1M/P.
Second, the resource points seem too high at 10. They get paid more than a city guard? But they taste the lash too? I don’t get it. I’d put it at 4 or 5. But maybe you’re picturing it differently than I am.
Last, you crammed in too many traits and skills. Take out theatrics for sure - read the skill description and sample Obs. Are these guys going to be applying stage makeup and disguising men as women? For me, intimidation would be out too - intimidation is a great way to make somebody stand down and win a confrontation without fighting. In the arena, your opponent’s not going anywhere - he has to fight you and he’s come prepared to fight. Keep in mind that your opponent is also a gladiator and thus a fearless gloryhound or whatever. I don’t want to look up all the traits, but you should pare it down too. If you want to keep in fearless, by all means go ahead. It’s good to have a trait like that available to tempt people to take the LP.
