There were some changes on the ONS Server. The Core's health went from 100 to 200 and eventually to 222. You don't get any points for destroying the core anymore and the points you get from building (and destroying?) nodes was reduced (half?).
As I've been playing for a while on this server and especially enjoying the berserk mode, I noticed some changes in the "behaviour" or the "strategy": As the points for the "non-fragging" were reduced, also the number of players caring for the outcome of the match decreased. At the same time, the numbers of "pure" spawnkillers and campers increased.
During some matches that I watched, there were pretty long intervalls, where no one was trying to build up the central node, but several players of each team were with their mantas at the corner node of the other team, and even as the central node was complete, spawnkilling was more important than destroying the corner node => central node gets lost => and so on.
In my opinion, teamplay has suffered a lot with these changes and I would recommand to increase the points you get for being a teamplayer, will say building nodes and attacking the core. The health of the core can stay that high, the losing team has more chances for a comeback.
But that's just my opinion, what do the other Onslaughterinos think?
