I'm currently a lvl 33 Mercs/Traps running at +1 and equal to two heros and enjoying myself.
Running alot of early morning, coffee drinking contact missions solo.
Truthfully, I have to do something stupid to ever be in serious threat.
I say go for it and enjoy!
The best day of vacation I ever had was spent playing CoH on a newly created toon right out Outbreak.
The wife and kids were at work and school and no one was there to bother me.
I.still speak of that day fondly!
