What should i get next ?

SHC and hero. If you want to upgrade your body armour further, get some Defender Gauntlets. I actually got Defender Gauntlets before getting trans, because they're a 4 body armour upgrade from Plate Mittens and cost no more than 1,5 million to craft. If you're going Royal Guard, work towards getting a Defender Shield. If you're going Zweihander, I guess it would be a good idea to get a Boarding Axe.

In my opinion, SHC -> Hero -> Defender Shield / Boarding Axe would be best.

Another thing you can do is sell trans and Plate Mittens, buy striped / heavy lamellar and then craft some Defender Gauntlets. Doing so would give you 2 more body armour than you already have and won't really cost you anything (assuming you already have the basic materials required to craft the gauntlets).

Hope this helps.
