Maybe re-enable masteries during prestige

Some masteries require certain talents. For example, Stukov’s 2nd mastery is totally uselss before Lv4.

Some PRESTIGES require certain talents. Raynor’s 2nd, Rough Riders, is literally useless until level 11 .

Or Vorazun:

• Prest 1 - emergency recall to nearest DP or Nexus: Emergency Recall is a lvl 13 talent
• (Prest 2 seems too weak, even though it’s usable from lvl 1.)
• Prest 3 - Prev Shadow Guards spawn at each Timestop. TS is a lvl 10 talent.

On the upside, you get DP’s at half-price and half-cooldown from prest 1 so may as well use that until lvl 10.

They should either re-enable Masteries during Prestige or make us get a certain amount of XP (1.2 million) without any mastery points but with our CO at lvl 15. It feels like quite a grind. And yes, definitely let us pick which Prestige we actually want.
