I’m also a knight main and I think buffing him would be a terrible idea. The knight excels in practically every situation other than the nest or LH.
A buff in wisdom is a bit unnecessary, because it would only allow permastunning to occur at even lower pet levels. I don’t think anyone would be looking forward to this change.
Giving the knight any extra attack is wholly unnecessary. Thinking the knight has a low damage output simply because he is lacking a buff is utterly flawed. With just a colossus shield and 200 mana, a knight can do over 3K damage. With an ogmur and 400 mana, a knight can do up to 8K damage with just his shield - meaning, with just his ability, the knight can deal roughly the same amount of damage as a pixie-wielding warrior affected by damaging and berserk.
On top of the absurd amount of damage the knight can dish out, he is extremely tanky. No other class allows you to be punished so severely without any repercussions. Sitting on an ice adept, for example, on any other class typically means a quick death or a nexus. If you’re on a knight, however, you can leisurely absorb this mage’s pixelated hellfire for as long as you please.
tl;dr: The knight excels in everything except for Lost Halls and the Nest. No buff is necessary; he can deal more than enough damage and can take many more shots than the average bear.
