ok firstly if kix relies on coin to make a profit its really simple  players want value for money  so make make the whole raid the cycle level like all siege, skirmish or assault and 4 monthly cycles again  set the targets from raid one dont change damage levels. and keep adding new tech . after each raid do a 4 day tlc every week for that cycle for players to get the new tech they need for all levels that way pillage is good to catch up .    make 40 targets map repair free and auto for new players to help them grind free so then they will spend on refitting new ships etc make the 60 targets maximum damage 20 mins so in base free repair to help medium players grind to get value during the raids then they too will spend on refits new tec  etc.  make the 80 sets maximum 1-2 hrs repairs depending on right specials weapons on new hull , the s target is the only target that should need U3 everything and make it 5 hrs max repair that way the big coiners can compete with each other on the leader board. they will spend on raids refits, U3 everything and they will still be best players in bp game
