Miniset is great but Protoss...

... really needed an extra neutral minion imho. There's way too many discounts for how many protoss units there are. I'm a bit bummed cause it really feels to me that all those discount cards are a bit wasted when protoss classes aside from priest play 2 or 4 protoss minions at best. Whereas terrans and Zerg feel like they're playing all their cards, Protoss feels a bit lacking, with only priest really using the potential of their discount mechanic. Artanis being a discount as well really feel a bit wasted.

I think if the warpgate location also added a random protoss minion to your hand on use, it would make the miniset for protoss way more cohesive for all classes. Obviously you'd need to lower the discount or the durability to 2, and possibly increase the cost to 5, but that's just a matter of tuning numbers a bit (i think given how weak protoss seems to be in early stats, you can go be aggressive and just nerf the discount to 2, it's a 3 mana nerf afterall). I don't think buffing the existing minions really would do much compared to adding a bit of extra minion generation in the faction. If you go and buff carrier and colossus for example, you just make the highroll of early warpgate/early discounts into big minion worse, whereas adding an extra minions would keep the highroll similar (if not worse if you reduce warpgate discount), but let protoss really get going and feel more inevitable as the game goes late.

Just my 2c.
