Premium accounts just arent worth it...

ARGO: Ok, I finally broke down and gave 250 gold to try out premium for the first time. I had read all these posts and heard all the complaints about it not being all that fair so, I decieded to go and see what all the hubbub was all about and heres what I found:
When I first got it I was really amazed at the nice flashy garage screen I got.....NICE. I had a IS3, VK360 I use my VK to feed my money hungry IS3 so I figured that I would grind a day and make enough to take the beast for a walk a little more often. The first 3 or four times I went out, I was amazed at the EXP/Credit difference, I mean WOW I had the IS3 in one battle in Prohovaka and I killed one Tiger II and my team won, I GOT 40,000 creds and 1,110 exp!!! My friggin jaw hit the floor! I was astounded. But alas, that's where the good times ended. I had to leave for a few hours and came back with a good 8 hours left on my premium and went in there and found that the only "Premium" difference was that I still had the snazzy garage. I went into grinding for the rest of the night and saw little to no change in creds / exp that I would have had in normal battles. Another thing was also noted, It seemd that when I started playing premium the second time, I got placed into some really lopsided battles for the remainder of the night. Coincidence? could be but I say this because I have heard the same complaint for a few others who live on premium accounts.
I am not complaining more than I am reporting this so the DEVs can look into this and see if I am onto something here. Other than that, I really do like that neat garage screen with the pretty music in the background. Perhaps they could put a scantaly dressed chick in there walking around and serving drinks and hors d'oeuvres .
