I think it really depends on the deck/player. For new players survival and wild are not really viable options. With a bot playing for me I won 14 rounds out of 75 last season and got less then 1 sps.
In the last brawl I got 27 sps, which with my average win of sps in modern is the same I would get from around 40-50 wins. Pretty good for lining up a few matches.
That said, there does seem to be a bit of an issues with brawls as it's often the case that less than half the people don't show up. In the last brawl I was in I had 3 of 7 show up. In one brawl I had only one opponent show up.
I think Splinterlands does have an issue with retention like many games do. People get bored, or frustrated because they hit a plateau that they can't beat without spending significant amounts on improving their deck or life changes and it just loses priority.
It'd be cool if they added some kind of PvE elements to guilds similar to the fight against the troll in the campaign. I also think we need some new gladiators.
What do you think would make Guilds more interesting?
