Positives:

1) healthier economy
2) Larger Playerbase (will make grouping better)

Negatives:

1) Server Mergers spell the begining of the end for a mmo... massive negative stigma. If they want the game to rebound... merging servers will drastically hurt this.
2) Massive population problem with the ps3 launch. (will have to turn around and bring them right back up, without a server transfer system this means some people will not be able to play with their friends)
3) Larger Playerbase (people refuse to party... so higher populations = less room in Behest and less xp over all on solo mobs.... until people wake up and start grouping up less people is actually better unfortunately.. the whole community issue with the game atm)



I see a merger drastically improving the current condition of the game honestly... but pretty much putting the final nail in the coffin for the game. so we will get a great game for the year or two before SE stops supporting it.
