It's not about making the game easier it's about making the game play more balanced. Defend it it if you must but AoE spam is out of control, all mitigation is nullified within seconds and because of cooldowns is virtually ineffective. Siege both defensive and offensive needs to be fit for purpose or remove it completely.
Here's an idea, have two versions of WvW, one for melee classes and one for casters and see which one is the more enjoyable.
While you are at it, remove thieves and rangers and we are good to go 🙂
Another thing people conveniently forget is in the beginning everyone reached level 2 and jumped straight into WvW and it was a level playing field. For a new player where is the fun? No gear, no masteries and probably a completely wrong build, are these players not entitled to have 'fun' too? The catching up is too daunting for many and yet people refuse to see the problems and try to pretend the game mode is fine as it is despite complaining about dwindling numbers.
WvW needs to be fun for everyone not just the hardcore players and I am talking from the pov of a player who has been in WvW since day one. Continue to cater for the hardcore players and the numbers will continue to drop.
There is nothing else out there to compete with WvW and I would hate to see it in decline because people continue to stick their heads in the sand and pretend everything is fine.
You could be really radical and have a single build for WvW classes then we could see who the good players really are when everyone is equal or reset everything but keep the levels as they are.
Radical changes are needed to keep the game fresh, Anet broke new ground with the launch of GW2 they need to do something similar now and reinvent themselves.
