ASW – Alternative hero leveling.

Therefore, the Stronghold unit will no longer be able to have the speed aura.

It's a trade-off. The Stronghold unit will instead have the magic speed perk, which is an even stronger perk. You simply won't be able to distribute all 4 super perks across a single school. Give up on at least one (the Pursuer). When I saw how you drastically improved an already decent perk, I was amazed. There are already plenty of combat perks in the log, and your additions make it even more so.
