Figure I'll make a thread that summarizes the best strategies I've found for outland instances. If people respond with good quality strats for bosses, I'll add then to the main post. Think of it as a one stop shop for your "OMFG I HATE THIS BOSS!!!1!!one!1eleven!1"

Arcatraz-

Zereketh the Unbound - Impossible to mutli-box IMO. Maybe with really high SR, but even with Priest SR buff, my team got rocked. SKIPABLE (Highly suggest just skipping). After about 15 wipes I decided it wasn't worth it. Deadly issues here:

1) Shadow Nova, Either LoS it or it hits for roughly 1-2k
2) Void Zones, 1k per second. If you're group is getting hit, strafe out or die. This combined with Shadow Nova can be VERY deadly
3) Seed of Corruption. Should be healed through really, 300 dmg a tick then explodes for 2k. SPREAD OUT :P
These combined are very hard to deal with. If you LoS the Shadow Nova, and spend too long you'll put a void zone in your LoS area. If you group up for too long, the see of corruption will get you. The Shadow Novas over a long time really start to hurt.

Wrath-Scryer Soccothrates - Not bad fight, pretty easy once you get the strat down. Keybindings needed : Non-tank group strafe left/right. Strat:

1) Put group at a good distance, and engage with tank. Dps down, while watching heals on the tank. Tank will take a significant amount of dmg due to fire aura. Tank the mob FACING the group.
2) If you did ^ ^ then when he knocks your tank back, its should be roughly on yoru group. After the knockback he's going to charge (laying down a row of fire). Strafe your group right/left about 20 yrds and heal them up. Engage with tank and pull him away from the row of fire. (Watch the row of fire hits for bigger then the graphic shows).
3) Replace the boss how you first engaged him. Rinse repeat


Dalliah the Doomsayer - Very easy fight. Just ensure you don't heal with debuff on, and interrupt the heals.

1) Tank with group away (she whirlwinds)
2) Keep tank topped off, so when the tank gets the debuff, it will be at full health.
3) Don't heal with debuff on, jsut wait (it's only 10 seconds).
4) On whirlwind, jump out and get ready to charge.
5) Right after a whirlwind she starts to heal, quickyl run in and interrupt! rinse repeat till dead.


Harbinger Skyriss- The encounter is the hardest part, but very doable. I personally got the Imp, then the sulfron, then blackwing.
Imp - Stand in melee range, dps down, and heal who gets hit with fireballs.
Sulfron, Keep Follow on, dps. When rain of fire, move mob. This is a run around like a monkey and use instant casts to dps fight.
Blackwing - Keep your DPS FAR away (blast wave sucks). Keep tank topped off for MS, and dps down. With 3 dps you can get down before final boss ( Note he is immune to fire).
Finally the boss. Right when he spawns, mark a raid target on him! Next follow this:

1) Engage with tank and start to DPS. Heal the dps that gets hit with the mind sear.
2) When boss splits, find the unmarked target and Kill it FAST.
3) Rinse repeat. Very easy if you kill the add quickly and heal the sears. Mindcontrols are just annoying, never had tank MC'ed.
