So many bullshit in this topic and so many players giving their opinion on something they obviously don't know ...
1h+shield was op 2 years ago, before they implemented the upkeep system. After that, 1h was pretty balanced and nowadays it's just fucked up.
Reason? Thanks to devs who wanted to nerf 2h's stab, 1hs have been nerfed (you think what i'm saying isn't logic? Me too.)
The only viable attack remaining is the left swing. Stab have always been a pretty inefficient attack and have been nerfed more with this "2h nerf" (actually i don't see in what way 2h have been nerfed, but nvm).
Overhead was a good alternative to left swing (weaker ofc, but still viable) but have been nerfed with the same patch, and is now pretty difficult to use (apart if the opponant don't move at all).
Right swing is pretty slow and can easily be outspam by a greatsword/polearm user (very logical too when you compare 1h weapon speed and other class weapon's speed, but nvm).
What's the point in being a shielder now? We need at least 3 hits to kill a guy with a medium armor (i'm not even speaking about heraldic/plate users), we can only rely on our left swing, sword users often glance (yes we often glance, mr "i know everything better than you" gtx). The only viable thing to do now as a shielder is to use a steel/military pick or a military hammer and spam left swing. Great.
Result? Leave shielding alone and stop saying big fucking bullshit like "overhead and stab were op, now it's fine", so you won't appear like a foolish stupid idiot (yes, it makes me rage)
PS : 1 advice for those who want to have a non biaised opinion about shielding : Make a 1 hander+shield alt, then play it at least 2 weeks. Playing it just a few days is not enough. If you play it 2 weeks, you will have the great occasion to feel the frustration rising in you after having being teamhitted more in a few days as a shielder than in a few months as every other class, after having being killed several times by noobs (who can barely block a basic feint) just because they spam with their 2h sword while backpedaling (that's what we call "2h heroes"), and so on (i let some suspens for those who want to discover how op shielding is).
