The respecc costs are not correctly shown.
It is said that the costs are 25k for the respecc per point. Which is partially correct.
BUT
The costs are actually 125k per point. 25k for opening the point again and 100k to distribute it to another one.
I get it, why it is not shown as it really is, as you only pay for freeing up the points again. But that is not what I understand as respeccing.
Problem:
The costs for respeccing are misleading. It isn't mentioned that you have to buy the SP again, which impacts the C-Bill costs (not the XP costs obviously because you get them refunded).
With the costs in mind it gets expensive quite fast if you config your mech in another way and want to have the right skills for your configuration.
This makes testing new things really bad

Possible solution:
1. Up the costs for respeccing to for example 50k per point but let the people keep the SP as an unspent point. This way it would still cost less to respecc ( 1 mio instead of 2.5 mio for a single weapon sort with 20 SP maxed for example). Which might encourage testing more.
2. Keep the respeccing cost at 25k but let the people keep the SP as unspent points.
3. Get the overall costs reduced by not refunding all XP but only a lower %... for example 50%. It would still be somewhat grindy but I personally feel much more happy with grinding XP than with grinding XP.
