So I was reading through the forums and I see some concerns with people feeling they need to level up EVERYTHING, which (in my limited game experience) tells me that I can level up everything. I had ideas, but I thought maybe it was best to just put out a feeler and see if people really see this as an issue? Oh, and my idea was to limit skill access based on choices in the opposing tree. So break skills into Tiers: 1, 2, 3, 4. As soon as I open up a skill in Tier 1 in water, tier 4 in fire is no longer accessible to me. When I open up a Skill in Tier 2 water, tier 3 in fire is no longer accessible, etc. This 'may' also be able to be done by putting affinity requirements on spells, though I don't know how well building up one tree really hurts the opposite tree to know if this would work.
