Well, I believe most of us have played for at least 2 years so we do have some experiences from first hand. I play tank, I play dmg so I can compare both. When Captain was released, Cortina was handeling it too well, it was actually difficult to win as attacker tbh. But in attack cortina was cake for Ron. [Ron was very effective in attack in general]. Then Sousa came which caused destruction and def was struggling to survive lol, Sousa was just slaying everybody. Leavenworth was introduced and? He can barely handle Sousa still. It could for 1-2 rounds but when you are standing against 10 duelers with sousa, well good luck to you, even builder or soldier with massivly high hp had problem. Even if you have leavenworth upgraded on 2 or 3, Sousa withh destroy you, unless you are builder. But speaking from experience, builder has no chance either now... Then Black heart came and, well, we know what is happening now. Duelers are too strong, they can crit very often now, and usually when team takes couple of low levels duelers, they crit et least once as well which affects you. Thus, do something with that stupid resistance. Kordiak and more upcoming sets need to have resistance, higher, so you can take under 1000 hit from dueler instead of under 2000. Also, I would personally change crit chance hit for duelers ONLY if they are on their own tower. Whenever they go away, lower down the % for crit. That could help giving hope to people and encourage them to be tank again, nowdays people go rather dmg than as tank, who knows why.................. ehm.....
Also, by making new sets, you have to imagine not FF 120vs 100 but 20 vs 20 thats usually what is happening on words 1 or 2 years older. Lets be honest, every worlds is almost dead after 2nd christmas. So maybe you can handle as tank soldier dressed in leavenworth between 2 other tanks with the same dress, but if you are on dead server alone next to a adventurer and builder and behind you are 3 dmgers, you know.... That thinking is kinda missing here. Not everybody comes from every year new full server, we are also veterans here, who would like to play but we cant.....
