I am a veteran MMO player, who started with Knight, MU, Lineage and the like (didn't like Runescape), played Wow for 10 years and EVE close to that with breaks for other games like Cabal, Requiem, Tera, WoT, War Thunder and many many others, now playing Crossout, Star Conflict and Dreadnought. The reason I mention all this is for you to understand that I have seen how classes work, I have seen "Assassin" and "Rogue" like classes before and never have I felt so powerless in dealing with them, and NEVER have I complained about a class on the forum before. In most games you have a fairly short window of burst that you have to survive or avoid, which has always been doable for me, even undergeared, but it is not the case in Dreadnought. Whenever I would die to a rogue in wow, for example, I'd see what I could have done differently in order to live, and then try and execute it the next time. In this game, though, you can't run, and you can't protect yourself, your only hope is to hope for your team to react and save you in 5 seconds.
I am currently doing the Dola grind, 20k off Koschei, and sometimes I feel like tearing my hair out, even though patience is something I have plenty of. Maybe I am not at a point where I can objectively evaluate how strong corvettes are, since my max range against a corvette on Dola is <1 KM and my only defense against a Corvette is to nuke us both while shielding myself. It works only the first time against any corvette pilot who is not a vegetable. Unfortunately, most aren't, so they learn to maintain a distance of 2 kilometers, making it impossible for me to hit one. Shouldn't destroyers be the counter of Corvettes? If not, what is? Certainly not Dola.
The other ship I normally play is a t3 tactical (the healing one, forgot the name), and I am spinning my head around constantly, spam marking corvettes all the time, and I see people trying and failing to shoot them down, then giving up and going for other targets instead. This is an unfrotunate situation, because I am hiding behind or below my team and the only way I can "run" is towards other enemies or away from my team, neither option being really an option.
I have seen people on forums complain about Koschei and how overpowered that is, but in most games I am able to sneak in from behind or below and suicide wreck it even if it's with another, lighter healer, placing myself between them.
But how on earth am I to deal with a t4 corvette of the same faction? It has 20k health and can survive a nuke while dealing 3x my dps at 3x the distance, while flying at a higher speed, having better maneuverability, having a drastically smaller hitbox that I can only hit at a distance of 800. I get it that the point of Dola is to make you suffer so much you wouldn't want a Koschei or you'd donate for exp conversion instead, but dаmn.
I see people here making the argument that "oh it's only the experienced players wrecking new players on covettes, any decent team would stop a Corvette from being effective", but as someone who plays solo in pubs all the time, I constantly see Corvettes atop the scoreboards with 10+ kills and 0-2 deaths, taking up 1st, 2nd and sometimes even 3rd places on both teams. So are you saying that these are the same experienced players wrecking the other 80% of playerbase? I feel they need to be adjusted but I am not knowledgeable enough yet to say how.
Take it simply as an opinion of a fairly new player.
