You mean Defense by 2 and Attack by 1?There's something a lot of people don't know about dex. Each point you add to dex increases your defence 1 and your attack 2. Say if you had 20 dex=20 defence and 40 attack.No dex no focus needed if you want to be a good tank..
Here's a L61 War, naked, with 15 Dex, 15 Attack and 30 Def.
