I was in the invance last night, we were very close to finishing it but I think we lacked organization. Yes the 100-120 invance is hard for those levels. Ive done countless 80-100 invances and we were able to finish with 6-7 people with 50 minutes to spare, no problem. The thing is, in 80-100, the toughest mobs (yeti,mcw) can be soloed easily by anyone in the top of that range (95+) with decent attributes so its never been a problem. In 100-120, i doubt there's many people that can solo a giant without any difficulties. That being said, I think the 100-120 invance is doable with less than 10 people if we are organized.
Here's a plan I suggest based on the invance from last night:
1. Once the invance starts, everyone should stay around the gate, easy enough.
2. Once the influx of monsters slows down (70-80 minute range), a team of 3-4 people (2 strongest fighters, 1 mid level and 1 ranger) should go around the fort to clear the mobs there, everyone else stays at gate. The top ranger should stay on wall. Simant (pro ranger) was doing this last night and it worked out great.
3. Once the back of the fort is cleared, people should go exploring. Form 2 teams and go. The only people that should stay back would be the gate keeper, the pro ranger and one low level player. You might think this is not enough but trust me, if you have a good ranger, you can take on the mobs that come. Last night, I was gate keeper and Simant stayed and ranged. Every time a nasp/cocka/giant came by and attacked me, Simant would teleport inside the fort right behind the gate and range the mob, didnt take much to kill it, he would be done before i ran out of mana easily. The only problem was nasps which take a little to take down by ranging. Thats why the second low level player needs to stay back. Once the gatekeeper runs out of mana, he can diss and the other player engages while the ranger keeps taking the nasp down.
4. Main thing for the later part of the instance (<50 mins) is that once the gatekeeper calls for help, we should not have the whole team come back. Thats what happened last night. All the people were out, close to docks, the gatekeeper called for help and everyone walked back, killed the one mob and then had to walk all the way back to where they were before. Thats just wasting time. I suggest that once the gatekeeper calls for help, 2 players call in channel that they will come back and help, the rest stay and kill the mobs where they are.
Communication and organization is the key for this invance. Im convinced we could have finished it last night with the amount of people we had if we were more organized. Talk to eachother in chan and lets make sure we have a plan before the thing starts. If anyone has any other suggestions, lets add to this and come up with a 100-120 invance plan so we can finish this comfortably every time.
