Im currently S1>P1>Hop1>Cata3>Templar, and gone full con. Level 126 with 25k hp, buffing to 32k with swash. ANd still crit for over 1k and have decent damage. (might be due to arde though).
I am building a full tank too. i am at lv 117 right now with full con and 24k HP. Finestra only give 2% block per skill lv so if you want to get 20% block from finestra you will need c2 of hoplite.
Just like everyone said, damage coming from others (DPS class). My char role should be just to buff myself and to tank. i am PVE oriented.
i am suffering from soloing with low dmg against normal and boss from map/quest but it is doable. Slow leveling but at the end i am leveling up.
This is my current build now with a lot of classes 
Swordsman>PeltC1>HopC1>CataC1>SquireC1>PeltC2>HopC2
PeltC2 of course for swashbuckling and guardian and max them.
HopliteC2 for Finestra and stabbing and max them (currently my main dmg skill)
CataphractC1 for movement speed, earth wave (2nd dmg skill for soloing) and mount (Bonus 25% hp and 8% or 10% both phy def and eva of companion).
SquireC1 for equip repair (i hate to spend money every time to fix my equips and traveling fee to the blacksmith).
I’m still thinking that rode is more pvp oriented not pve, i might be wrong. Some like the cc but my understanding is that you are tank and your job is to taunt and keep yourself alive to reduce a healer job so healer can focus on team member. Tank that is easy to die when he/she tanking is not a full tank.
Let the DPS and other do the damage and cc skill. You dont want to use skill with knock back to scatter enemies you try to taunt and gather.
Currently using cloth set for magic res and magic dmg reduction bonus since you probably will block most phy atk anyway with high con and finestra plus the “C” button but magic atk cannot be blocked. Swordsman get the highest phy def per lv compared to other class so you shouldn’t worry about phy def.
Phewww after a long story of my tank life, that is my current build.
it is not the best but i enjoy my tank. Cool HP number, i like when my char mount the companion, lots of block notification (block, block, block), Spear FTW.
Sorry if anything wrong with my grammar, english as 2nd language user here.
Any critic and suggestion is welcomed.
