Well not really.
It was pretty much not about races, most likely about classes.
For example, i started in C4, last days, so let's say C5. Back then the best dagger was the TH cause he had Dash, making it able to catch up on targets and kill them. Let's not forget that daggers had huge dmg output but low defenses.
The dark elfs always had the highest dmg due to their STR and skills (Hex, for example), which allowed them to be a problem, but all the dark elves are slow. Speed, atk spd and casting speed wise.
Archers right now are bad, as i said earlier, the guy is a meme but you can see that's there's a little issue when a lv 83 dies from a lv 79...especially when the lv 83 is full A grade and the 79 is C grade.
Same goes for mages...i never feared a mage. And i'm an SE, i'm basically a mage myself...but i'm way stronger than mages cause i've heals, debuffs and good buffs.
You can say they land debuffs and turn tides...i can tell you that you would have killed the titan w/o the mage. The nukers debuffs doesn't decrease the HP potion effects, means that worse case scenarios you can have them using DOTs like Ice dagger if SPS, poison if SPH and Inferno or w/e if Sorc...but i really doubt that's enough to burst a melissa user.
People rerolling to daggers cause they've seen the update, which made Titans weaker pre-85 and made them weak against daggers with the Rage skill (which is a must due to the +40% p.atk...but also -30% resistance to daggers)...also Titans lost their immunity to debuffs from Frenzy and M.def boost in Guts.
On the other hand, daggers damage was boosted on frontstabs, while nerfing the backstab but w/e. As you know, the only reason to go backstab was Focus death +90% dmg from behind...but you were suffering a -30% dmg from front. Which was a huge nerf cause you could PROBABLY try and land 1 backstab once every 7 seconds, maybe.
Also Wind riders earned "critical damage" passive which is a HUGE boost to them...+ dodge skill, ggwp.
But noobs like those guys from GreyLotus on Elcadia, which are basically nonfactors PVE-players, are just like the average L2 players: play the OP.
So now that titans got nerfed they all ran to reroll to daggers. In my case i had already SE+Dagger XPing as my main was always dagger, but they were bad and SE was just too huge for clan activities like PVPs. And then some people have the guts to tell me "eh you play dagger cause it's OP xdd", dude, i was Othell Ghost Hunter on awakening servers when we had 1 dmg skill only. With 1 skill working only on bleeding targets, the bleed skill with 20% land rate and the last dmg skill that could full lethal the target but had 30+ seconds delay.
