The easiest way to defeat Lord Rathari

Several ways:

• Quick travel to spaceport (cooldown 30 minutes)
• Use the emergency fleet transport (cooldown 9/12 hours for subs/F2P, reducible to none)
• Use the flashpoint transports (no cooldown)
• Travel to your stronghold, then to fleet(no cooldown)

I played a Powertech in beta and now play a Vanguard (Trooper equivalent). At your level, this is how I'd recommend taking on an Elite enemy:

1. Make sure you're at full health and are using your Combustible Gas Cylinder (CGC)
2. Start at range with Unload
3. If CGC proc'd and Rail Shot is available, use it while running towards the enemy. Rail shot will always be your highest priority ability, so use it whenever it's available.
4. Use Explosive Dart
5. Use Rocket Punch as soon as you're in melee range
6. Use Rapid Shots when your heat is around 50% to allow it to regenerate.
7. Use your Electro Dart now to stun the enemy for a few.
8. Stick to Rail Shot, Explosive Dart, and Rocket Punch while in melee range at this level.

My final tip is to make sure you're always doing something! Don't waste global cooldowns trying to figure out what to do next; get used to your abilities and see what's available and what isn't.
