yeah you covered that partly, worth considering not allowing countries to vacation for 72 hours after leaving a tag though

what id want to do however is i was going to run a tag to abuse clan gdi is have multiple tags set up, maybe 3

then id have each tag join clanGDI and have 1 clan leave GDI every 1 day people then farm the bots in that tag

then they leave that tag and join the next tag which has already been in clanGDI for 2+ days

that way you can always be farming bots during a short window and be safe from all hits for most of the time

with someone being on irc ping alert or whatever to instantly join the tag back into gdi when hits started

but the whole things going to be such a logistical nightmare that it would only work in ffa 1 man tags probably, where you would be running your topdown FA'd countries, techers, demo resellers whatever as the non/limited grabbing countries

and yes having an ingame foreign affairs diplomacy system would be great of course for multiple reasons!

i liked your suggestion on 72hr exception for retals, woud be good to be able to manually set a country to retal only for player hit/clan wide, extend time if needed for FR reasons, set cripple/farm/kill statuses

and in the new UI would be great to have some of these things show up as alerts or notifications

ie "there is a retal available it expires in 38.4 hours" or "3 current kill targets, please hit" possibly with alliance suggested recommendations of x hits/member although with how small everyoens got thats not really a thing anymore

and of course hopefully you can do your formal clan wars stuff with it :)
and even use it to generate stats that include spy ops done in wars!

not expecting everything at once of course
