I currently have 3 mains:
Bird-55 Best Gear
Mage-52-Crappy lv51 gear with cheap Gurgox eye
Bear-52-Kinda Free Cyber and Mysterious Gear

I am currently finding it hard to lv all three to 55 with out elixirs and after the devs nerfed the easier xp requirments to level. I am thinking about focusing on my bird only and forget about the others and lv them later.
My question is...what are the pros and cons for focusing on one main?

Is it a problem to you guys to get top gear for all your characters?
Do you want to improve kdr stats on 1 character? Or all?
Are gp supposed to be spent to get top gear first before saving up?
Isn't it better to be specialised in 1 toon or "multitoon-functional'?

Thanks for the help, Im having a hard time deciding.
