I'm a social butterfly; I don't solo from 1 to 32 when leveling, I generally put up LFMs for anyone to join (unless I'm going AFK a bunch because of real life distractions). And at cap, I run in full parties zipping thru r10s with my friends. The choice between repeating the same quest over and over again or having to solo to get kills isn't a good trade-off choice. Punch is a bad design for a MMO where people are encouraged to hang out with other people. If punch did something as simple as letting party favors drop in any chest (for the person using it) then it wouldn't be an anti-party mechanic; but as it is currently, it actively encourages playing the opposite of the gamestyle I enjoy.
I still dont see where giving soloists the option for Punch would decrease grouping
People who want to group can still group, and its still better rewards/minute than punch
People who want to solo can do so and get favors
People who want to group and not run the Challenge can still do so, because right now that choice offers zero favors
If you're upset merely because people would have an
option to solo, even if there's no
incentive to solo because the rewards are still better while grouping...then I'd say I am not here to be your content, and I should have the choice to go solo if that's what I prefer
