I’ve thought about this too, I understand that SG wants the titans to scale to the level of the members of the alliance, and creating a bridge like this would throw off calculations for next titans, if strong players are regularly assisting in lower level titans. It would probably be a massive project, but it would be nice to have the option to “Link” alliances, then there could be two chat tabs, one for alliance members, and one for all members of linked alliances. That way you could chat within your alliance, and also with members of the sister. You could also create another tab for Titans, under the alliance main page, for linked alliance titan. That could give the option to attack the sister alliance titan without leaving your current alliance, avoiding the chest lockout. To compromise with SG titan calculations and deter multi-titan farming, they could only allow one attack per member from a sister alliance, and removing all loot and chest progression when attacking a sister titan. This would keep loot the same, and chest progression the same, but allowing linked alliances to give support to each other. My ideas could be flawed, and have massive loop holes, but something like this would be great. the main thing i would like to see is chat integration between the alliances. Most mains and feeders are setup to build and teach lower players and have the graduate to the main. It would be a great deal easier if the experienced players could give advice to the new/growing players without having to jump back and forth between wars, creating second accounts on different devices, or using third party apps to chat between alliances. Just my 2 cents.
