Is there some reason, I know not logical, but I'll accept any reason as to why they reduced the number of times to do challenges to one? Are they attempting to completely alienate f2p and very small casher players?
The zeta upgrades available in the ship challenge, were something that even f2p players could be able to increase their characters. Without purchasing any in the credit store, we could be sure we'd get at least one character zeta'd a month. That time has now doubled. As well with the regular challenges. The 3 for some 5 for the others ensured that we could get equipment that would enable us to advance. Now that it is only one time, it will be ridiculously impossible to gather up equipment for our characters or for the relic scavenger.
I really hope this is not a permanent thing, as it won't make me or any other f2p player spend money, and may actually turn some people off completely, if they are never going to be able to advance at all.
Whale chasers may pay the most, but there's not enough of them to ensure this game continues.
