I'm new to this forum. But when I read about battle tower few questions and ideas immediately comes to my mind:
Defense bastions:
Aside from necromancy/alchemy etc. platforms, will there be also some defense bastions (equipped with balistas/scorpions or other war machinery)? Maybe I'm wrong but my idea is based upon official info - tower will be "ancient structure" and "player has to conquer it". So I imagine that the Tower (not from London :)) is part of some bigger defense ancient system and it served as protection against some monster race, maybe even dragons. So I would expect lines of walls, gates and towers (equipped with balistas) that protect cannyons, passes and key roads to the country. Main battle Tower could be just the base from which you can teleport to these outside lines of defense. Defense bastion armed with machinery has its crew ("platform dudes" as told in official info).
Imagine this quest - you got info that horde of enemies supported by dragons is going to attack your defense line.
1. You have to find area where they have been recently spotted (ask villagers/others), then scour the area, find them and watch them (probably from above in dragon form) to know where they are heading.
2. Then quickly prepare defense of that threatened point. Your task is to destroy ground forces - then dragons will run off. But they are strong supporters. So...
3a. Order crew in defense bastion to aim the dragons and shoot them. Then you will fight enemies that breach the wall or climb upon the castellation. You can succed when you concentrate on killing ground forces, but the dragons are very dangerous when you are in human form. Of course the crew will help you a little and hurt some dragons.
3b. Or you can shapeshift to dragon and attack all yourself. You will have more chances against dragons but you will be more directly attacked (by ground forces - archers, mages and dragons). And you wont have so clear view of the situation on the walls. Your dudes are weaker and can be defeated by enemies.
3c. Order crew in bastion to aim ground forces. Its dangerous because nobody will attack dragons but crew can help you to kill ground forces and win the fight before dragons will kill you.
3d. Alternate - You could crew balista yourself and shoot out some dragons or ground enemies and then defend walls in human/dragon form.
So decision is up to you. Does it sound interesting to have some defense fight vs dragons?
Battle tower quests:
Will there be some quests directly related to battle tower? I mean something like fixing broken machinery, repairing broken walls, exploring dungeon of the Tower etc.? I had one more intricate idea. Imagine that you mix some potion in alchemy platform, go off, fight some enemies, drink this potion and - what the hell is going on??? It poisoned you! And its getting worse with time! How it can be?
1. You have to prepare/find a cure for the poison. Sooner the better. (It can also be curse)
2. Return to battle tower, ask your dudes. Suddenyl they found out that one of the ingredients is tainted! A traitor! One of your dudes is traitor.
3. Try to catch your traitor by some clever way (for example you can mix some potion, leave it on the table, leave room and...)
4. You uncover that traitor is dominated by some strange power. It seems that there are hidden doors and it leads to unexplored dungeon under your alchemy platform. And strange is that it looks like dragon cave. But why would someone build alchemy platform above dragon cave? Was there something to hide? And who was the founder/builder of the platform? Nobody knows? Its also weird. Now you will slip into the mystery and start to solve this unexpected bigger quest...
Its just an example, but I think it could be interesting for have a traitor in player's battle tower. Most players would not expect that. What do you think? Could it be interesting quest in Ego Draconis?
