Training Camp to lvl 25

Of course, this would mean stronghold to 25 as well, but that would open up possibilities for other buildings. This specific idea revolves around the training camp. I’d like to see color specific summons similar to the elemental summons portal with a small chance of a past HOTM pull (random). You can make the chance for a 5* less than the portal to keep the revenue stream avenue, but it would add a new level of decision making for the players.
