The most important balance points
Totally agree for the passive abilities remarks. It´s toxic for the players skill.
For traps the can add such a detonation: first player put the trap and after when the player wants he could activate the traps (like mines)
Pets are problematic because they do a lot of noise and damage without any controle. Ranger pets are amasing just spam one attack and the pet change, where is the difficulty? Normally ranger or necros have to fell like puppetmasters.
You underline the tankability of certain classes (scrapper, herald,reaper, dh,…) with agressives amulets. Maybe it´s because the number of immunity are too high (block, evade, etc etc) and they can easily survive after the burst part.
The balance is not here, why a cele tempest does more total damage than marau rogue for example? Because tempest could dps and tank in the same time.
I must underline the fact that balance is not just between professions but also between trait lines. Is not normal that in pro all classes run a unique build! Anet, a balanced class is not a class with ONE viable build. A balance patch is not to nerf a build and make another viable!! All trait lines of each professions have to be competitive and balanced.
When you give to a class all dispel tools or buffs bot tools in a one tree, the classe become forced to run one build.
Example: the actually chronomancer: inspiration for healing/assist/dispel + chaos for boons (stab+ prot) /defense and chrono
Same for tempest water/earth/tempest
Scrapper elixir/alchemy/scrapper
Herald retribution/corruption/herald
Etc etc
Conclusion: in pvp dispel, boons, assist, defense for the win. (Rogue/war are usefull in those part so they are excluded for the pvp).
