This is about as credible as you can get. Have YOU played kRO2 extensively to say otherwise?This is what you said. See that quote? "WEBSITES." Not 1 guy from the SEA RO2 fourms. You need something far better than that. It's called credibility.
Check your sources properly next time. Also don't use a plural or say websites when its a random forum post.
Also calling me narrow minded yet YOU are the one saying there is only 1 tank viable. Look in the mirror first.
Unfortunately due to the setup of this game and the way bosses work later on, it'll gradually become the most viable tank. Maybe there might be combinations that can work without 2 Knights, but 2 Knights offer the most safety without sacrificing additional slots for more tanks.
You still don't want to believe it, that's fine. Leave this thread then. No need for you to be here, if the mods don't think this thread should exist they will delete it themselves, you're not the police around here.
