So maybe the swordsman itself is the problem?
You’re only just realizing that now? No one likes taking swordsman in ET, str or not, and if they do they probably won’t even succeed. Atm, swordsmen aren’t good for ET at all.
I don’t know where you’re getting the 'Full Str in ET" but from what i have read, and i’ve read alot, “swordsmen are fairly useless in ET” are what people are saying, with a notable exception of High con Pelt squire, since squire tanks can fix your gears, provide useful party buffs and is just generally nice to have around. Many people have done ET with no swordsmen in their party. It’s 100% doable.
My build is not for ET clearing but for GW and battle league.
You can’t dodge magic so wizards are just going to melt you. (But they pretty much melt everyone anyway. You just die faster.) You can definitely have a good time killing full str or str/con swordsmen because they’re gonna have trouble hitting you, and some archers, since the whole class is weak against cata in general (can’t kite them, can’t knock them back), though
why on earth would a full str or str/con swordsman ever PVP is still a mystery to me.
GvG will most likely be a nightmare for you because most pvp guilds i know prioritize getting cc wizards/archers/ plague doctors, but I’ve seen Str/con SW3 Catagoon doing extremely well in pvp with a plague doctor babysitting him.
Battleleague is probably where you will shine the most if you are up against certain lineup. Little magic damage, cc…etc. Wizards are also getting nerfed in ktos so sw3 Catagoon ( and swordsmen in general) will be much better, but having full dex means you won’t benefit much from the recent STR buff to swordsmen, but if you’re going full dex you probably don’t care about that anyway.
