Update 0.2.4
Doing a round of bug fixes and balancing, before moving on to advanced classes and other features.
After this I'll try to stop myself on further balance changes as its taking alot of time, and might not matter anyway once advanced classes come out.
There's still alot of issues remaining, including memory issues, storage and party bugs, those are pretty hard to track down and I'll fix them as I go.

Fixes/Improvements
Fixed attribute exploit
Fixed being able to move during animation of attack, cast (physical skills) and pickup (might make it feel more 'clunky' but I believe, like flinch, its important to have and brings the game feel closer to RO, plus it makes ranged spam less OP)
Fixed multiple weapon element cards bugging out
Fixed some bugs regarding range
Fixed monster spell circle area being wrong size
Fixed haste not curing slow
Fixed bugs with calculation of -hp/mp
Fixed being able to have negative hp/mp
Card element now always overrides armor/set element (like Sanctified)
Fixed counter doing no damage if you have no Reflect stats
Fixed summoned bosses dying instantly if spawned on damage aoe
Fixed warrior dual wield skill sometimes not working or appearing in 2 spots
Reduced bloom/brightness in Forest Maps
Fixed Vitality Aura still being applied after taking off Codex
Fixed enemies not being able to hit you while chasing
Fixed boss drops being common rarity and disappearing asap
You should now be able to view Monster Info when dead
Added DamageFromRanged and DamageRanged to substat pool (also fixed red text coloring for Arrow Catch Wall)
Fixed gaining Twohand stance bonus from Books and Maces
Added visuals to Demonic Wail
Reduce server auto restart threshold, as it was sometimes crashing before it could restart

Weight/Storage
Bank weight increased (10k > 50k, not that it matters)
Character weight 2000 + 30 * lv (instead of str)
Reduced weight of some items (equips around 50%, boss lures 10 > 1)

Trade
Fixed being able to enter negative gold, or more gold than you have, and screwing up the trade
Gold value now formatted for better clarity
Fixed being able to change items/gold after clicking ready
Fixed items visually disappearing if trade was cancelled

Balance
Removed hit/flee cap of 95%
Bosses now heal to full health if out of combat
Ground aoe can no longer trigger autocast (closing this can of worms)
Monsters now avoid spawning near players
Attribute points reduced (100-130 = 2 points per lv, 130-150 = 1 point per lv, overall you get 70 less points)
Reduce monster hit growth by around 33%
Life/Mana on hit now provides flat value + scaling (reduced combat knife, brimblade, bat lord card values 5 > 3)
Removed base crit chance of 5 for players
Removed stat scaling from monster skills (was throwing everything off, this will reduce normal monster spell damage by ~50%, boss by ~30%)
Reverted +33% atk / -33% matk change from last patch
Monster ATK per lv greatly increased, about x2 @ Lv150
