Hey all. Here to suggest 2 things that would both result in a small amount of power creep as well as additional build variety. First thing I would like to suggest I'm calling "Golden Milestones". Upon hitting lvl 40 with a Civ, you can select one of their milestones to affect EVERY other of your civs. Kind of inverse of what we have now, instead of selecting milestones from other civs to benefit your current civ, you select a milestone from the current civ to benefit your other civs. While this would result in a bit of power creep given that you'll get 5, soon to be 6 extra milestones for your civs, it would also help with build diversity somewhat since the "Always take this" milestones, such as Celtic Crit, Nordic Armor, or Egyptian Build Speed milestones could be chosen as the "Golden" Milestone and then you can select the second-best milestone for each specific Civ (Such as Infantry Bonus for Celts, Range Bonuses for Greek, or even just good economic milestones that just don't outpreform the BiS Milestones). Second bit of Power Creep I would like to suggest is a "Free Advisor" Slot - Basically a 5th Advisor Card slot that you can put ANY Age Advisor in. The Advisor would still only activate in his given age, but you could have 2 Age 1, or 2 Age 4 advisors, or whatever.
