Release 2.2: bugfixes\balance

[list] [*]fixed bots getting stuck on some levels [*]fixed an error which caused Chakram (Khan), Boomerang and Sniper shot (Shaggy) could behave incorrectly when colliding boss missiles and Sigma’s Warhead [*]fixed Dave’s rocket jump [*]improved PVP medkit, healing amount per tick increased from 50 to 75 [*]fixed cursor behaviour in the main menu when using a gamepad [*]improved spam detector in global chat [*]fixed an error with readiness confirmation in empty group [*]fixed visual bug with quick clicking through pages in hero shop [*]fixed an error, that sometimes led to game freezing after reconnecting to battle [*]fixed visual glitches in main menu and battle interfaces [*]fixed text display in certain languages [*]fixed an error when sometimes inactive players weren’t kicked from battle [/list] [h1]Balance[/h1] [b]Shieldmaiden[/b] - currently Aedis is the strongest and the most popular hero in the top. We’d like to keep her unique playstyle, but fix a combination, that guaranteed killing of any enemy in almost all situations: Cyberarm + ‘Executioner’ axe. Changes: [list] [*]epic axe with armor reduction got the effect increased from 10% to 15%, and damage decreased from 60 to 55 [*]epic axe with bonus on stunned enemies got the bonus reduced from 40 to 30 [*]'Executioner' axe got its attack speed reduced from 1.5 hit/s to 1.2 hit/s, bonus reduced from 50 to 40 [/list] [b]Chemicals (Khazak)[/b] - Those are absolutely the best second slot for the Hermit. Chemicals deal huge AoE damage, that can be further increased with certain skin properties. Area of effect and duration are also significant which increases chances to successfully hit multiple targets and creates “zoning” effect, keeping the enemies away from it. We’d like to preserve the control nature of this gadget, so only the damage will be changed, which is reduced from 270 to 180. [b]Other changes[/b]: [list] [*]instant damage of Guardian (Khazak, Skaar) increased from 80 to 100 [*]invulnerability duration of Protective barrier (Khazak) reduced from 2.5s to 2s [*]reduced damage of epic knuckles with no critical attacks (Khan) from 65 to 62 [*]increased magazine of 'Avenger' machinegun (Arnold) from 30 to 40 [*]'Hellfire' flamethrower got the magazine reduced from 10 to 8 and reload time increased from 1.5s to 2s [*]lowered armor reduction effect of Predator visage (Khan) from 50% to 40% [*]health restoration of Cestus gauntlet reduced from 35 to 30 [/list]
