Lots of useful ways to use Defilers! Submitted by Goldenjack9! Thanks!

DEFILERS ON THE OFFENCE!!!!!!!!!
PLAGUE!!!!!!!!!!!!!!!!!!!!!
1. First of all, be sure to upgrade burrow, consume, and plague! THESE ARE VERY IMPORTANT!!
2. Second, try to plague without getting too close.
3. THEN BURROW OR RUN
4. You might want to bring along some lings for a tasty snack!
5.HAVE FUN! Plague really ticks off terrans, hurts toss and hurts zerg! It's very very good!

DEFILERS ON THE OFFENCE!!!!!!
DARK SWARM!!!!!!!!!
1. Be sure to upgrade consume and burrow!
2.Dont let the defiler get to close to your destination(they are weak).
3.Be sure not to let the swarm have any open spots.
4.Zerglings or ultralisk seem to work best with the swarm.
5.Dont let your units get out of the swarm.
6. Bring some nice munchies for your defilers.
7. HAVE FUN!!!!!!!!! Dark swarm has been named the cannon killer! I love turning toss cannons against themselves wit this:)
8.Dark swarm seems to work best against protoss. It does work against toss and terran though.

Defilers on the defence!!!!!!!
Plague and dark swarm!
1.When being attacked by melee attackers DO NOT USE DARK SWARM!!!!!!! Only use plague. Be sure not to get your own units with the plague.
2.When being attacked by air units by all means use dark swarm! Use plague too.
3. Run some hydras and/or your dfiler under the dark swarm.
4.Be sure to upgrade all of the defilers moves!
5. this really ticks off protoss, BAD. With this move ive held off 12 carriers. Several times. EASY.
6.It also works good against battlecruisers.
HAVE FUN!
