First of all , i want to thank you for your comment.
As L2Archage , we appreciate any kind of feedback people gives to us , since we are still under Testing Period.
I should mention tho , that critisism (a thing we always welcome since we believe it helps us to become better) to be productive requires solid points.
I highly doubt if posting a screen shot with someone asking a technician about in game features can help us imrove or help the community get a clear idea about our server.
L2Archage Developing Staff consists of a considerable number of individuals , each specialized to their field.
For in game features the best idea is to ask one of our GMs in game , on Discord , or even post to our Forum (we reply fast).
To answer the main question of sEtEki , L2Archage will include combined buffs (Improve Combat / Chant of Critical etc).
And to answer your main question we do know basic and even non-basic and detailed things about Hi5 and Lineage 2 in general.
We welcome you try L2Archage either now on our Testing Period , or after the Grand Opening.
