The problem with less people in parties means LESS leve links which takes a huge hit on everyone SP which I imaging is exactly why SE implemented this.

8 Party limit will screw a lot of LS's. We already have to cut like 5 players when we start our NM events due to the 15 cap. Dropping that to 8 just leaves more people excluded. Not all NM's are so easy with only 8 people.

There was NEVER anything stopping any group from inviting a whole 15 for those whiners. Don't like the 15 man parties turn your damn recruit off and go with 4-6-8 or whatever.
