Universal costs for spells

[Simonh2000]

Can you explain to me how lowering the costs would make the tree worse? You said you would have an extra spell to buy, but... how is that bad? 

Instead of doing 15 + 15, you would do 10 + 10 + 10 and thus have an extra spell. An extra spell you could choose to keep or not on your bar, an extra spell you could slot in specific situations... so you would have more flexibility? Something, I know it isn't your forte but anyway.

the math on this is simple... in the case of armed, as jumpy said, you're spending another 5 rpp for an armed stance. that in addition to the 20 rpp cost of dash strike means you'll need another 25 rpp spent in addition to reach armed's intermediates. phantom strikes (15 rpp) + anything else you'd want (10 rpp) would then get you to 50.

if phantom strikes was 10 instead, you'd end up with 45 spent in that same scenario, and you'd need to buy another spell to reach the intermediates, costing a total of 55 rpp. you'd be spending 5 more in that example, not less
