Kailasa has very good recruitable mages and better sacreds. This guide describes heavy usage of summons which are recruitable in Kailiasa, and Kailasa has won two games recently. Coincidence?
Also, how Bandar Log is 'better' at using its troops than Kailasa when it needs to summon support mages instead of just recruiting them is beyond my understanding.
Ghandarvas are a decend mid-game unit, and?.. Your recruitable troops are still terrible. Some rather expensive summons dont make your army shine.
Siddhas, a high-end summon, can offer you air magic to cast some essential spells like arrow fend, not to spam combat spells. Two or even three thunder strikes arent that big by the time you can summon siddhas.
Once again, I'm completely puzzled how Bandar Log is better suited for using Siddhas.
I agree that Bandar Log depend on their summons... because summons are the only good thing about Bandar Log. And Kailasa has some of them as recruitable troops.
