Core is never going to be viable in competitive is it?

[Deniara Devious.3948]

Here is my list:

1. Kits should do 10-15 % reduced damage when elite trait line is chosen. This could allow minor buff to kit damage for core without making the elites too strong.
2. F5 toolbelt skills need buffing e.g. reduce cast times/delay, cooldown significantly. Elites don't have F5 toolbelt skill, so that would be the skill the sacrifice for elite.
3. Improve the least used trait lines: tools, arms and inventions.

1 & 2 are both just number tweaking, sometimes requiring some change of animation as well, but overall wouldn't require too much work from Arenanet. #3 requires much more thinking, testing and planning.
