I had a lot of fun in WAR, it really was a fantastic game... well, before end-game anyway. Then it was just zerging mindlessly.
I had a static group that played twice a week at specific times on specific days. We used voice chat to communicate. We used add-ons that maximized our efficiency so we could all switch to the same targets.
We started out as 6, but after a couple weeks our 6th had to drop out for RL obligations. Then it was our 5-man consisting of 2 Warrior Priests (Melee healers) & 3 tanks (one of each race, with me being the Knight of the blazing Sun) to Guard them (so they took half-damage). Our organized 5-man repeatedly took on groups that were much larger - it was not uncommon for us to face off and win against 4-6 times our number. It was epic, it was fun, it was challenging, it was GREAT.
It's a shame that didn't carry on post-level-30, but that's why we'd just roll new characters and start over again, until our group split up.
I have good memories of WAR that will last for a long time, it's sad to see it go, but I know it's time.
