Guild Wars 2

Karma Training can be good and bad
Cons – seeing the map an enemy colour just so your team can turn it back for the rewards, an endless chameleon of change.
Destructive to wvw incentives of keeping territory, not deliberately giving them up.
Pros – Gold Loot and Karma these make the world go around.

PvE content Annoyance
Cons – Distraction, little value, only obligatory reference to current living story content that has no relevance in WvW. PvE blobs getting wiped out by WvW zergs
Pros – introduces new players to wvw (karma train does this more effectively and for the wrong reasons), allows wvw vets to get the odd living story achievement, which they can get outside of WvW. WvW zergs crushing oversized blobs of PvE karma hunters.

Achievement hunters
Cons – arduous grind for some, PvErs forced to gain AP by spending hours doing content they never did before, just for the points. WvWs going for the chest reward which was mediocre at best, distracted players from productive gameplay in WvW.
Pros – your AP grew!

Group matching
Cons – unbalanced, you had some grps constantly steamrolled, other grps that had mostly difficult brackets while others had Easy mode.
Pros – Got to fight different teams that you never had the opportunity to fight before,

Open ground skirmishes between Zergs
Cons – Running away to let siege do the talking rather than your abilities of open zergs vs zerg battles
Pros – Some awesome battles wins and losses, feelings of highs and lows.

What did I learn, Season 1 Had its fun moments, long build up battles cut all too short, tempers flairing, grps despairing, cheering and re rallying, plenty of whining, winning losing, and stalemates, theres plenty that can be changed, adjusted.

I learned that players are passionate, confident, resolute. They demand from you what they expect of themselves, I learned to admire the Commanders who took on a mostly thankless role, to the support players who watch empty towers for enemy movements, to the scouts that spot something interesting while out roaming, I learned how frustrating wvw can be and how it must weigh heavily on players who come every day regardless of season rewards, slugging it out against enemy servers. Constantly teaching sharing information, giving other players boosts in confidence, and of course the opposite of the above as well.

I am by no means an avid wvw participant, I take it with a grain of salt, and dabble.
I claim no expertise but only an observation.

thank you for sharing
