Considering the pero-value of the voting tickets, I don't see voting tickets as very valuable. As a prize for an event, they might as well put 5000 pero or something, neither is any reason to go for the top rankings, they were unnecessary extras as a prize.

I think the vote could use some improvements:
1) Categories. Seperate votes for N, R, SR, and occasionally SR-limited girls.
2) A larger selection. This first time, we had 3 SR and 3 R to choose from. Well, obviously, places 1, 2 and 3 were taken by the SRs, and the vote was really only about which SR we would vote for. One was well ahead, and there was some minor competition going on between #2 and #3, probably from people hoping that the #2 might appear in the rGacha as well. But overall, the race was already over after the first 2000 votes.
3) With a larger selection, set more cards as winners to bring into the rGacha. The last rGacha was too much a repeat of the rGacha before it. The more variety between the gachas, the bigger the chance people will want to play. Very few people will bother if there's only 2 cards they don't have yet. Even less people will bother if the "new cards" in the rGacha are from events that ran less than 2 months before, because, they will already have those cards!

rGacha tickets are relatively hard to aquire. The cards in that machine should be relatively hard to aquire as well, but currently, they'r rather recent and relatively common.

At least the new voting set has a good variety of stuff. Downside is only 3 will even get chosen even though for once I actually need a lot of the girls, basically anything from egacha. It'd be nice if they did top 6 get chosen.

Top 2 or 3 from each rarity would be fine. Also a limit number of vote per account.
