They said, eventually. But also, you’re not able to respec your points. So, let’s do some napkin math:
6 Tiers, 4 Skills per Tier, 3 Points per Skill = 12x 6 or 72 Points.
Considering the projected Max Lv is 40, that means you’ll need to find a lot of Skill Tomes (and maybe some quests will offer +1 Skill or something as well). Personally, I think it’s a good system.
You can change your build (for free, any time from what I hear), but you cannot respec your Skill Points. So if you dump 3 points into Blizzard, that’s where they stay. This means if you want to try a fire build instead, you aren’t moving those points into a Fire skill.
What I would do, is think about a build I think would be fun and put in 1 Point per Skill, per Tier until I either felt like I needed to invest more in something or I think I want to try another build, but I would be trying to save as many points as I could until I was certain of which path I wanted to follow.
Like they said though, eventually, it won’t matter because you can have 3 points in every Skill. But starting out, it would behoove you to be frugal; or use them sparingly.
