Actually, the problem was 100% from switching weapons, not armor or accessories. It had to do with the [at the then time new] passive procs / stacking buffs. It allowed you to take all the high powered, long CD skills, and cycle between weapons with only passives and 'common skills', and once the high powered buffs ran out, swap weapon, and pop the next high powered CD.
An Example.
Back then you could get Berserk on a Champ.
Pop it, and Soul Wreck.
Once you cast SW, you Swapped to Axe, used Final Strike,
Swap to Spear, pop Longinous, and Dodge Down,
Swap back to Sword, and SW again,
-Repeat Cycle-
Or
Crossbow Scout:
Pop Guard/Reflect, Use Stun Arrow, Web Arrow, Poison Arrow, Daze, Status Downs
Swap to Bow
Impact, Phoenix, Stun -had separate CD's back then...-, Status Downs, Poison, Ice until Stacked, Camo
Swap Back to xBow,
Repeat.
etc etc.
There was just a lot of issues with how it was launched.
Armors, thematically, I feel is pushing the limit? I can understand having an 'off weapon set' in some games, or a gear loadout, but I have to agree with Cortiz and say being able to switch jewelry should be enough to add some strategy, without making it about who has the most sets in storage for maximum potential problem solving on the fly. It, just get's messy.
Soooo yea, gotta Agree, Jewelry seems fine, not so much a fan of the other stuff. -even though I do miss my hybrids, sincerely-
