As another member of the TxS alliance I would like to point the fact that this patch will present issues at several ways, not only at big alliances kills.
Fixed spawn times are a double edged weapon. You will force people to concentrate on the map at the same time. But you are excluding a lot of people for those events. For example, 19:00 may be prime time for some parts of Europe, but for others it is dinner time.
Also, while the Megaserver system you will be addressing the emtpy maps. It is making more difficult to organize guild events (not only megabosses kills). As we cannot choose which instance of the map we will be joining (the megaserver will choose for us). This is aggravated in the case of multi-guild multi-server runs (like TxS Teq/Wurm runs).
Even more problematic is linking Teq/Wurm spawns to merits. This heavily impacts the current guild ecosystem. People will have to choose to give resources (merits) to the guild that organizes megabosses or their other guilds. In my particular case, that means that if I want to collaborate on the Teq spawns I need to ditch my real life friends during guild missions runs. The last thing small guilds need is to have more competition with big guilds.
Summarizing you are removing removing from us the freedom to choose when do we do megabosses and with whom do we do it.
I understand the need of the megaserver, and I actually like the idea behind it. I am not a fan of the idea on tokens to spawn bosses costing merits. What I cannot wrap my mind around is why limiting spawn times so much and why fixing them on such an odd times (at least for some of us).
