GK certainly does need some changes, but just taking a hammer and bashing it on his head is about as fruitful as nerfing weapons based on their pickrate. The absolutely no choice part and the focus on stacking power are then issues.
The whole second row is lunacy.
Heroism does not increase stagger. Knightly Temper has ZERO synergies with anything. It doesnt even grant THP on Kill. Virtue of the Ideal is the only choice right now and one I dont enjoy, nor that has a place on GK. You shouldt be able to deal with trash easier than Merc.
Line four is also a mess.
I never liked the RNG part about GKs passive. 10%, or 15% more Power dont do anything for you if you cant bank on getting it every time. The CD regen seems pointless and the combination of 10%DR and passive hp regen for the whole group to strong.
Further putting points into an RNG system is pointless. The only real choice is Strength Potions.
Everyone levels with Grims in their hands and alot of people dont use, or learn to use Potions until they are far into cata. At that point having on demand Potions is taking the difficulty out of every difficult situation. The amount of Patrols and Monsters is limited during normal runs. Your Pots are not.
Line five is the biggest mess.
Joust is incredible and there is no point taking anything else. Discipline is overkill, does not eat the only defensive Talent spot GK has and is hard and finiky to activate. Stoicism is just bad. It doesnt help at all with GKs weaknesses, which are dot damage from specials and getting stuck via lack of movement.
The last line also doesnt offer much choice.
Impetuous Knight is a gimmick. If you wouldnt need to kill something with your Blade first for the speed to activate, it would still be a gimmick, but a more useful one. Audacity and Confidence both make me shake my head.
Both attacks offer far too much stagger and CC. At this point its easier to gravity kill monsters with GK than with FK, whose main purpose is to be a Battering Ram.
Ontop or that one enables you to take a dump on CW Patrols and Monsters, while the other one Ruins Zerker waves and SVs. Then there is also the absolute randomness of Confidence. You might kill what you want to kill, but most of the time you gonna catch some slaves, kill an SV and just toss Zerkers all over the place because your skill is not allowed to do damage after a certain cleave number. You utterly lose the ability to control whats getting killed.
His Talent tree is a complete disaster compared to most other careers. But that is not even the end. What is a GK worth without the Mace&Sword and Executioners? Nothing. Absolutely and utterly nothing. Slayers you can find running around with 2hHammer, DualHammer, DualAxes, 1hAxe, Coghammer, 2hAxe and everything will do its job because Slayers Talent/Passive/Ability combination makes that possible and promotes all those weapons. GK already has a limited weapon pool and further eliminates most of them by design.
The whole ājust slab more power on himā Idea is working, but its also promoting a single playstyle with no wiggle room whatsoever. A more diverse Talent tree would be much appreciated, especially since its a ānewā career.
