Something that holds many new PVPers back is ISK and the desire to make up for their lack of experience with expensive ships. Experienced PVPers love this because it gets them more juicy kills and loot.
Here's the truth:
It doesn't matter how good your ship is if you don't know how to fly it!
It's far better for new players to stick to cheap ships. Hell, many of the best PVPers in the game fly nothing but cheap T1 ships.
Because you can fly and lose more than 10 Battlecruisers for the price of one Tech 3 Cruiser. Cheap simply means more action.
To learn you need to lose ships, so why not lose cheap fully insured ships?
Here's a challenge for both new and experienced PVPers... Buy 10 Rifters (or if you must another races T1 frig) and go out and PVP with them until they are all dead. Fight everything you see that you have even the slightest chance of killing.
Go ahead... Do it!
I promise you will be a far better PVPer when you are done, and the whole thing will probably cost you less than 50 million ISK.
