DRK vs WAR.

Basically almost carbon copy of eachother outside of defensive kit and DRK having more OGCDs to make it feel more fluid and dynamic.

Both are really good. However the biggest difference between the two is that WAR is significantly more self sustaining that DRK. At end game you can see WAR being favored simply due to the ability to cheese tank busters more frequently than the other tanks.

I love DRK but WAR seems to be the favored tank by the devs followed by PLD.

Play whichever one you have the most fun with.
