The description of the monster linking system reads:
[dev1131] An enemy linking system has been implemented.
The system allows an enemy to call for help based on the strength of the party that engaged it. Enemies will link when:
Clearly this is NOT how it works. It's based of Party SIZE.
If you're in a party of 8/8 you can link up to 8 mobs, party of 4/8 only 4 will link.
At low levels where crowd control is an issue linking 8 mobs (without power level mind you) is nearly a suicide mission for the party. Especially when targeting mob up to +10 levels above the average PT members level.
I'm sure it's difficult to make an algorithm to calculates the strength of a party VS the difficulty of a player.
Maybe the game can calculate the average level of the players and link mobs based on that.
If average level is equal then the link is 1:1 (1 mob per 1 PT member)
If mob is 10+ above average PT member then only 1 monster is pulled regardless of PT size.
Max mobs pulled is reduced by 1 per 2 empty PT slots when mobs are 3+ levels higher.
-10/+2 above PT average level 8 mobs max
+3/4 above PT Average level 6 mobs max (4 mobs max in 4/4 size PT)
+5/6 above PT average level 4 mobs max (2 mobs max in 4/4 size PT)
+7/8 above PT average level 2 mobs max (1 mob max in 4/4 size PT)
+9/10+ above PT average level 1 mob.
(unless monsters are in a planned "group")
Currently even in high level areas pulling monsters is very chaotic (though easily defeated because most monsters are near or just above player level)
When starting to fight monsters of higher level it would make the pace of battle much more fluid if people weren't presented with too many targets to Tank, melee, and nuke on.
However I feel that getting away from amount of monster links based on party size, and base it more on strength (level/calculated attack power/calculated def ect ect) would benefit the EXP process greatly.
