-1º - sorry if i made any english mistake -
In my experience in game, i've seen a lot of players (almost everyone) using wolver/gunslinger itens ( skolver,snarbolax,vog cub etc... ), because they offer decent defense like chroma,skelly,jelly,angelic and it offers bonus damage ( agaist everything ) the others sets i mentioned offer bonuses too but only in specific situations, thats okay, some players prefer gettin sets for specific situations, but the ones that wants to be balanced have to use wolver/gunslinger equips, in my opinion more sets for every situation would increase player sets diversity, making more uniques players, wich to me means more fun.
sets reducing charge time would be nice, maybe one reducing damage in trade for defense, sets that offers bonus in several situations instead of one ( like arcane salamander that offer bonus against beasts and slimes ), sets increasing atackspeed,charge reduction and damage ( all low, maybe one medium, maybe 2 medium, any way it dont get overpowered or underpowered) would make more balanced knights for every situations... and things like that..
also i was thinking about a new variant ( or even a bonus from sets ) that increase shields health.
Again. sorry for bad english, i hope it was understandable.
If English is not a fluent language for you I highly recommend using the forum closest to your natural language. If you are using a translator check with someone fluent in both English and your normal language to make sure it works.
Yes, there are clones. Those other armors are underused because Wolver and Gunslinger (SDemo is also up there, but there are very few bombers) reward use of a specific weapon type. Creating more situational armor like Chroma and Jelly will not make the already underpowered equipment any more appealing because they still have very little advantages in versatility and practical use when a player has to decide what to invest their time and money into.
Chaos armor gives +1 charge and +1 damage for all weapons per part. Mad Bomber and Volcanic Demo give bomb charge time reduction bonuses. Swiftstrike is a shield which gives +3 attack speed for all weapons. The Seerus masks give +2 gun charge time reduction each. These things exist.
Almost all shields of the same star rating have the same amount of health. Shields also already regenerate within seconds even if they were recently broken. A UV improving shield health would outsource the only advantage Omega Shell line has.
