Tower 1:
Knights Templar with Holy Strike, Ancient Oak Spear, and Mithril ArmorI know, I know. I used KT for the base tower. Wait, before you lynch me, I can explain.
It's not that I think the tower is actually good, so much as I realize the value of their base medium armor. Since MA from the Dwarven Hall grants 2 tiers of armor to the Dwarves, it would presumably do the same for the KT. Therefore, at full MA upgrades, the KT would be either immune to physical damage or have like 90% armor instead of only 65% like other high armor upgrades grant. Now, we all know that KT have extremely undesirable base attacks, so the other 2 abilities that I've given them are for the purpose of buffing that. They have Holy Strike, since it gives them sufficient damage in melee battles, and it is aesthetically pleasing. Their second ability, AOS, is specifically for the twofold purpose of succinctly dealing with those annoying ranged enemies with lethal True Damage and softening up their adversaries before engaging them in combat.
Tower 2:
Bladesinger Hall with Life Stealer Strike, Whirlwind Attack, and CounterattackThis tower is all about retaliating against its opponents. LSS from the Renegade Post grants the option of regaining the HP that the warriors may have lost when CA didn't kick in. WA from Barbarians complements their main theme with a chance for strong AoE damage when damaged. Finally, CA makes the Bladesingers nigh invulnerable with its massive dodge chance and subsequent repercussions upon the offender. This may detract slightly from the effectiveness of WA, but it is still desirable to have it nonetheless.
