I am currently at level 150 following Rugal’s Lord Knight build. I was wondering if it was viable to go cataphract 1 instead of doppelsoelder at rank 6 to have more mobility and pve skills. I’m a real newbie at the game and would appreciate any suggestion 
I am a Swordsman 2 -> Hoplite 3 going dragoon for rank 7

o crap, i did the same mistake , thx to rugal my doppel 179 is plain useless late game, i highly advised picking peltasta instead of dopel or cata, cata c1 isn’t good nor bad, but peltasta will help you more, (when you use a shield increase your block rate, pdef by 35% and let you hold c to block wich is great against archers or another swordsman, Swash is the best for grinding solo and even better in parties plus works greats with hoplite finestra) i highly advice you to pick peltasta if you don’t want to reroll or suffer the lonesome of leveling solo after 230, you could pick doppel for c7 wich give you cyclone that works great in pve and pvp, dragoon it only adds dps to your pierce attacks for pve purposes, honestly i find doppel better for your case than dragoon, dragoon might give you the cool clothes and let you use 2h spears but you did the same mistake as me of reading his awesome guide with some random numbers and a lot of theorycrafting thats a different thing in reality, but in the end is your pick, not gonna lie, restrain at lvl 5 is still good(20% chance to stun with each hit for 1 min and a cd of 2min combined with pain barrier 10 but at the same time isn’t that great on easily kiteable targets like a swordsman), not gonna lie, pick pelta then doppel if you want a fun and functional swordsman late game for pve and pvp, going doppel or cata then dragoon is nuts for pve sake.
Thanks. I will be taking this into consideration.
Well as far as Cataphract goes, there’s a few skills that only work while mounted, and a lot that will not work when mounted. I built myself around that but for what you’re going for, I’d say pass on that. As for Peltasta…you get swashbuckling. That’s it. And some other defence stuff, but nothing in terms of dps. Do you want to be more tanky? If not, absolutely go Doppelsoldner. Though I wouldn’t go as advised in that build. Cyclone you definitely want and same goes for Deeds of Valor. DoV basically increases your atk and atk speed the more you get hit up to the stack cap which is the level of the skill. It also reduces defence, but it’s well worth the trade seeing as defence isn’t really a game changer the way it works. Also I’d recommend 1 point in Double Pay Earn. There’s a trick you can do with it in group boss fights. Get the boss to about 20-30k HP then pop DPE and let your party finish the boss. It will count when the boss dies and you’ll receive +100% base exp. So if you’re using token and exp tome, instead of 160% exp, you’d get 260%. This may be a bug atm but I’m not totally sure. But do it for DoV and Cyclone as they’re one of the best atk buff and AOE attack in the game.
