Quick MA/LA Ryleh researcher question

[ano]

You definitely want purple spawns (priests) when you play LA R'lyeh as they don't get mad, cost less upkeep and are far better on battlefield (D ones can spam Nether Darts, E ones are useful for forge, W ones can spam Frozen hart and S ones are simply good S2 mages). So once you have money you should stop building Star children and switch to purple Starspawns.
Blue Starspawns are not cost effective researchers, but they are splendid mages.
