Considering we did pretty decent last age with a full human tactician attacking core I'm pretty sure Persain is trolling when he says Tactician is garbage.
The fact that you can plan all your attacks to return before/after enemy waves is insanely powerful. It is a lot of micro management, but our war against Ruthless we were going down hard... until we got a "free" wave with 5 attackers hitting after their wave, and would return before their armies came home. Giving us 5 masses on a previously un-targetable Halfling Rogue.
The flexibility of a tactician is awesome, the added perks of being able to NS 2-3 days into war due to no thief losses and/or the added CS just to force enemy mages to keep MV-ing you (this goes for all personalities now with Paladin around) is awesome. -20% attack times gave it a lot of flexiblity (dont like the -15%).
That said, I guess we all have our preferences, but to say tactician is garbage is simply not true.
