Apart from the saddest PVP Truth of them all (that lag/performance is awful), here are 3 other sad PVP Truths and solutions that create happier alternatives for improved gameplay.
1) Buff-bar swapping is a "must."
Current PVP game mechanics discourage unique weapon combinations and diverse combat, and instead encourage us to use one weapon/skill bar as a buff bar (or "slave" bar) to pump up our character's damage and defense. Now of course no one is forcing us to utilize a buff bar, but we are severely hampering our effectiveness if we don't. For example, using just 4 out-of-combat skills (Mirage, Immovable, Rally, and Relentless Focus) on my back bar and activating them will carry the following buffs over to my damage bar:
- 20% evade chance
- minor resolve
- minor ward
- major resolve
- major ward
- 5 second immunity to knockdown/disable
- major brutality
- heal over time
- minor berserk
- minor endurance
Solution: A skill that provides a buff must be slotted on the character's active bar for the buff to remain active.
2) Sneaking/Hiding is encouraged.
The wide open, rolling fields of Cyrodiil are a good setting for a massive, three-alliance war to take place. However, current game mechanics encourage sneaking and hiding in these wide open fields. Instead of being given more obstacles/barriers to hide behind to break line of sight, we are encouraged to crouch in a field, in broad daylight, and ambush enemies that cannot detect us from a mere 8 meters away - which is an excellent tactic because sneaking and hiding allows you to get all those aforementioned buffs active (and regenerate your resources) before you attack an enemy who has no idea that you're invisible, in broad daylight, 8 meters away.
Solution: Extend the detection radius of all players to a reasonable enough distance that makes sense in open field, broad daylight areas.
3) Evasion is a no-brainer.
A cheap and easy skill to cast that gives every single build in the game a 20% chance to dodge attacks for at least 20 seconds. If you're not running this on your previously mentioned buff-bar, regardless of your build, you are gimping yourself.
Solution: Force users to have at least 5 medium armor pieces equipped to use this skill.
