Where a buff to resistances is nice (adding a 8 armor and magic resist when near an allied tower) I feel it doesn't really help that much when you are feeling the pressure from dives(which is really needed early on when you are being focused). I myself generally run Tanks of some sort or another, and I think perhaps some sort of shield maybe, a lengthy cool down on it in addition to the minor buff to resistances would help when you are getting tower dived. The trigger for the shield could be once your health dips below a certain percentage. You could base it on health or lack there of. The balancing would be tricky but it would be a nice feature. Also a buff indicator would be nice so one could tell once it was gone. I would appreciate the constructive thoughts of the community as well as any feedback from Riot.
