Five was already too few and restricted what I was able to do without feeling like I was missing out on bounty opportunities if I decided to enter the Crucible with Vanguard bounties running or vice versa so I would avoid doing that which impacts my decision making process in a negative way since I have to complete my "chores" before changing things up as I felt like it. And then it got worse. I recieved an Exotic bounty which cannot be completed until the RNG gods are kind to me (I have to dismantle 10 blue or higher rarity fusion rifles! FML) so that left me with only four open slots. Then I got another Exotic bounty (fortunately not quite as ridiculous but will still take some time), so now I'm down to three open slots on my Hunter. I don't even care about the experience part of the bounty rewards at this point; the items I have are already gaining exp way faster than I can possibly obtain the Ascendant materials to finish their final upgrades but being unable to efficiently multi-task my bounties will cut into my faction ranking progression which is kinda sucky yo. If the Tower didn't take so long to load it wouln't be much of an issue but that's one loading screen to get into the Tower to get new bounties and then another to return to the wilderness/arenas, it's at least a two minute round trip, if I swap out my bounties twice that's four minutes doing not much of anything, six minutes if I have to do it a third time. The time spent not doing much of anything quickly piles up as the available slots get smaller due to longer exotic bounties eating up space.
