I bought a lifetime subscription approx. 2 weeks before the 20 % off sale, and before my regular subscription expired, also all ship costumes, all ships except the Galaxy-X and D'Kyr, and all costumes and the TOS Bundle Pack.
I am willing to even buy the Emotes for more PvP content. :p
I am even okay with a 50:50 split PvE/PvP if PvE investment is spend on revamping Exploration Sectors so I never have again to meet Borg in search of artifacts of their 3rd Dynasty, and if Klingon Tribble-Killing-Spree content is reduced to 10 % of its current value. Oh, and Advanded and Elite enemies become more interesting to fight by more effective utilization of more powers.
PvP is very slow these days and might die if nothing is done soon
Unfortunately, all you really did by spending that money is encourage the devs to make more of the items you bought with those tokens. This in turn means they'll spend even less time improving the areas of the game that need it the most, such as PvP and KDF.
