ESO PvP battles are now more like dances than fights. They are long and boring. You have damage, you do damage, but you don't see any scratches on your target. The reason is not the target's high skill. The game allows you to abuse the mechanics with stacked HoTs and shields that make group members almost invulnerable, but does not provide any means to counteract this. This is no longer PvP, it is more like GvG, where the solo player is just a spectator. You stand on the sidelines and watch an absurd situation where two groups attack each other but can't do any damage. The following suggestions will help solve this problem, or at least mitigate it.
Suggestion: All shields with multiple targets should depend on the amount of magicka of their original caster.
Explanation: Shields with multiple targets (like "Barrier" or "Magma Shell") should be the sole responsibility of the healer. He has to make a choice: be an effective healer with maximum magicka or be a tanky but ineffective one. This will prevent situations where a healer has 40-50k health and 30k resistance but is still effective. This healer will be the main target to focus on in PvP.
Suggestion: Remove stacking of HoTs of the same type with multiple targets (non-AoE). Update their durations instead.
Explanation: This is a broken mechanic where HoTs with multiple targets (like "Echoing Vigor" or "Radiating Regeneration") are stacked together in a group and give them a huge total recovery. Combined with multi-target shields, this makes them practically invulnerable. Even when two such groups attack each other, they can't do anything.
Suggestion: Improve "Negate Magic" ability, make it prohibit the use of any abilities (also for stamina). Add a speed slowdown for Players inside.
Explanation: Despite the hybridization, this ability still only works on magica abilities. But you can cast any stamina abilities (not just Core Combat Skills) inside it and survive (like "Vigor", "Bone Shield", or "Ruinous Scythe"). This seems strange considering its high price. Another problem: it is difficult to use against a moving target. A small slowdown (40%) would make it more reliable in PvP.
Suggestion: Increase damage from siege weapons against Players by 30-50%.
Explanation: Due to the critical damage META and unbalanced damage of the reworked DK, players are using more tanky builds. Siege weapons are ineffective against them.
Suggestion: Rework Slippery (Champion Points Star), make it allow Break Free for no cost (similar to Expert Evasion).
Explanation: This star does too much as a star - it plays for the Player. It breaks CC-based combos and makes fights longer. There is the "Fearless Fighter" set that does the same thing. Using the set to get this advantage is a fair price, but not for the stars' use.
