By restricting the units and making the side offers for those units this feels like the most blatant coin grab going. They might have given the Rhino away as a freebie after the Jaegers but it's useless for the event 'as is' and a stupid amount of gold to get it to Omega. I have lvl 18 Ghosts but Osiris is only lvl 10 so the last base on either track is a touch too far for me. I haven't got the heart to grind the lower bases time after time to try and get the lower xp returns for tokens. Let's face it, the speed of troops mean every base is a ball ache and the event prize will b out of date soon after I stop typing it's really not worth it.
