Why not make purchasing unlock nodes a tiered cost?
Adjust the numbers as you will, this is simply an example:
0-10 100XP/ea
10-20 300XP/ea
20-30 800XP/ea
30-40 1,200XP/ea
40-50 2,000XP/ea + 100,000k cbills
50-60 3,000XP/ea + 150,000k cbills
etc
Balance it so it's still the same overall amount of XP and cbills to unlock all 91 points. This would keep many things the same as we currently have and allow people to experiment with different builds early while they're still feeling out a mech without costing them a lot of cbills. By the time you're hitting the last 30 points, you should know what role you want the mech to fill.
Leave respec alone at 25k per redo. That sounds fair for now.
