What's up Guys, this is BestTackle and this strategy has worked very well for my 3v3 team and eventually helped us getting Vengeful Glad. title back in s3.
So basically it throws off the targeting for the other team. What you have to do is name your character another class. For instance let's say you run a team with a mage, rogue and priest. Name your mage "Rogue" your priest "Mage" and your rogue "Priest".
Now, when the opposing team is trying to tell his team mates to "burst mage, cc priest," it may throw off the other team's coordination.
BTW. The name is of the class is probably taken so you can throw an lol or an alt key code in the name, or put "the" in front of it, or your partner's race in front.
ie.) Magelol
Máge
Themage
Humanmage
if this is in the wrong section, sorry.
