actually that is more enough to beat the enemy in DC and on world mapCdM lvl 14, TA lvl 11, CoA lvl 11 and Zeus lvl 10. That's peanuts.
if a player knows how to fight and is not a autobattler
(btw: fighting starts with selecting the correct troops )
in my side worlds I don't even have the TA and the other only on level 10 and have no problems
