"but MLG players dont use add-ons!" You're not MLG and you never will be. You're here getting gibed by warriors and hunter's cheese comps. It's pretty obvious where you sit on the totem pole. Download GladiatorlosSA and spellalerter. learn to use them, as i will reference them later.
these will TELL YOU when the warrior is about to blow you up, so you can be ready.
-Only trinket when someone is going to die.
Unless you can get a kill, or your team is going to lose a player, do NOT trinket. Stuns are annoying, cyclone is annoying, poly is annoying; DEAL WITH IT. Unless they CC you and blow cool downs, you should not trinket. If you do, this will put you into a longer CC chain and they will most likely blow everything they have while you sit there helpless.
-Learn to fake cast.
If you're a caster and you really need to get a spell off, start casting it before you need to, then cancel it 1/4 of the way through. Mages are the hardest to juke, because bad mages don't focus, and good mages prioritize. However, melee will almost always kick anything they can. You can also cast a spell from another school to make them burn their CD, then cast a spell from the school you actually want.
-learn to not get juked.
If you're on a healer, and hes at 100% HP, and so is his team, why the hell would you kick a heal's cast? stop it. More than likely, hes going to turn around and repentance/mind control/cyclone you. Even at 50% hp, wait for their cast to get to about 75% before kicking. Most heals now are instant cast, so you can very likely kill a "too pro for school" player as he fake casts himself to death.
-Coordination and timing is key.
Use your CD's and trinket's with your partner's. If you ever lose to a team who rushes in and blows everything all at once, you are bad. But don't worry, you can get better. You should always be ready to use your defenses when they use their offenses (thats why you have the skills you do) but rarely use them all at once.
