The 3 trees cost 1+2+3+4+5+6+7+8+9+10 = 55 skill points each so 165 skills point to have all at level 10
If we follow same pattern rank 1 = 1 skill point , rank 2 = 2 skill points then we get :
1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20 = 210 skill points
maybe less points for but there is not really need to reset if I understood we will reach the top in each category
