Class Choice problems

[Renly]

So the problem I'm having is I have just reached heavy longbowman and was having little fun playing it, while I like the idea of being an archer I keep getting very few kills before I am inevitably one shot by an enemy archer. I have also been getting annoyed with the fact that until my team decides to group up and hide behind cades I have very little opportunity to get any assist exp.

As much as I like the idea of being an archer I am seeing other Infantry and Skirmishers having much more fun than I am currently and they seem to be gaining levels a lot faster too. Any advice on what class I should consider etc would be greatly appreciated as I really do love this game and want to find a way to enjoy it more.
