When you reach all perks to level 6, it becomes not so fun to play anymore. So do not hurry.
If leveling takes too long, you should advance to higher difficulties. My advice is switching to Hard when perk level reached 3, and to Suicidal - on level 4 or 5.
whereas I see no chance how I will get my Firebug & Support even close to Lv. 5.
Damn you Mr. Perky achievement !
EDIT: As for medic, level 5-6 is a massive gap and i'm greatful from promotions on Valve's end for bringing in the newbies as that's a great way to boost your healing grind capacity. I've probably healed more HP's in the past week than i have in the past 2 months because of the potato sack promotion. The same can be said for the Christmas promotion.
Couldn't agree more. I have 100 hours and only have 3 classes at level 3, all the rest are below. Takes far too long in this game. I can't play higher difficulties because starting out with just a pistol when I join mid-game = death.When you reach all perks to level 6, it becomes not so fun to play anymore. So do not hurry.
