Thoughts and where I can improve?

Where can I improve? and should I take out some faith and invest it elsewhere? I don’t really use a lot of the incantations I got other than the buffs and heal. The weapons I fuck with are Flamberge, great katana (🤮), Queelign’s great sword, Mesmer soldier’s spear, and a iron cleaver (gods second gift to mankind). Also, I was told that the dragoncrest greatshield talisman is worthless for pvp, is that true or was I lied to?
