You do realize that you referenced stats and skills or whatever in the same thing, acting like they're the same thing?
Yes, you can raise int a shitload... but you can also raise, say, dex a shitload. And you can put points in dex AND ranged.
The point we're all getting at is that requiring a talent to use a weapon effectively, and then making it less effective than just hybriding out your stats is a bad idea.
Yes I realize that, hence acknowledging a ranger invest fully in dex and Ranged would have a 50+% damage advantage over a zen archery mage fully invested in int with no points in ranged (which, of course, a mage could still probably afford 2-3 points in Ranged anyway, plus Huntsman, which would benefit spells and ranged alike).
And while that's a significant damage differential, relative to the effect of attributes (a 150% damage bonus), the zen archer would not be really that far beyond the pure archer in terms of damage. Thus, the zen archer would have both potent magic and physical damage at their disposal, which is a versatility that is very strong with the current armor system. Sure, it's just a talent to use a weapon effectively. But it would grant access to both powerful spells and strong physical ranged attacks.
I mean, maybe it isn't as strong as I think it is. But I don't think it should be underestimated. Just looks at the power of staves. The way a 2-handed warfare char can easily swap to a staff to do massive magic damage with rage, the most powerful magic damage in the game, really, shows you how good easy access to both types of damage is. Presumably later in the game good staves will be gated behind intelligence requirements, and since strength doesn't increase staff damage, this strategy won't be as good. But if a warfare could use staves as well as physical two-handers late game with just strength investment, damage mages will be basically obsolete as they are now.
Hybridizing the current way would lead to a MUCH greater reduction in damage for both magic and ranged attacks, not to mention a lack of memory to take advantage of all the skills.
All that said, Zen archery would need some way to distinguish itself from regular dex archery, and I don't think an +AP cost with +accuracy is quite the way to do it. I'm not sure what would be right solution, but some way to embed magic into your arrow shots without turning them into worse wands would be cool.
I knew this would be a can of worms
