Interesting comments above.
Im level 19 Runepriest at the moment and have fell into the Scenario trap also. I made an effort to complete every quest in my book, but a few problems arose a couple of levels back:
a) The travelling Vs. Reward wasn't worth it
b) Getting groups together is impossible, as a healer, soloing is eye-wateringly painful
c) The rewards such as armour,etc is inferior to what i can buy from Auctioneer/Reknown merchants.
Scenario's are fun, action-packed, occasionally tactical. I am very motivated by the leaderboard, getting rewarded for my healing. If my side win and i concentrate, usually get 9-11k xp. Side lose and it's a quick game it's 5-8k xp.
I also get reknown points with this, so my Reknown Rank is currently almost 18, when my normal rank is just 19.
Do my share of keep raids though. Yesterday was a classic example of what you must do:
Firstly, get a PvE group together and start attacking a keep, just the NPC's outside. Then, people see it's under attack, slowly join your group. You then find the enemy appearing inside the keep attacking you. You tell others there's enemy players there, more join; likewise for their side. Result = You get a full raid. (Then lose in my case)
Besides that yes, very quiet and without a guild or good active friends list, this game would be very lonely. Years of grind mentality taking it's toll, making friends ain't on the list anymore. Though, if like me, you can get a guild who are similar levels, with similar playtimes and free time as you, it becomes somewhat better.
