If anything I’d drop Bash, Umbo Blow can provide knockdown and would allow you to raise Thrust more, Pierce type damage becomes very important overtime, yes it has literally double the cooldown of Bash but generally your party should AoE the knocked down mobs faster than you need to use it a third time.
Shield Lob is simply not a good skill, you literally lose your shield until you walk to pick it up or wait until it appears back in your invetory, this may not be an issue early when you can easily get two of your shield and can just use Weapon Swap for a new one, but later on when you begin to use Jalia Kite Shield and Sage Wall you may not always have two of it to keep your tanking AND capability to use all your moveset on point,with Swash Buckling the mobs come to you anyway and let’s be honest here, no one is getting hit by that in PvP, making it even more pointless.
Guardian honestly simply doesn’t give enough defence to be a skill worth investing in, the damage you recieve nulify it really fast and other defensive buffs such as Aspersion outclass it right off the bat, seriously Aspersion is so good it literally makes Guardian a waste of a point the extra evade aside., not that you are going to recieve any significative non-magic damage with High Guard and buffs, also high Guard’s Defence Increase Atribute.
I’m still not that versed into stat distributions, so I can’t help that much there.
Dunno on the cooldown of base camp either.
The last skill on Peltasta C3 to be more precise:
It was changed to Pierce in the last patch just so you know, not sure how many hit it deal though, probably around 3-5, seems to be the standar for this kind of skill.
