I support choosing a hero (of course, with Luna banned) and unbanning mages. Set up a poll or something. Just because no one complained doesn't mean the guys don't want to play by different rules. If you don't set birds and don't take Luna, this town's usability can drop to the level of Tower (or even lower).
Well, exactly, often playing Conflux comes down to this: did you build birds in the first week or not; if you didn't, then everything is terrible. Upgrading mages allows for a more varied build strategy!

If choosing Luna as a starting hero is banned (similar to Gosh in Necropolis), then I'm also in favor

As for the other bans on Conflux, I think the following: phoenixes with 21 speed, faster than Archangels, immune to fire, and with a growth of 4 per week — definitely imbalanced, they can't be allowed in their current form, unfortunately.
Regarding the upgrade of butterflies, I would allow it, since often the 2nd level isn't built, and upgrading butterflies on day 111 means losing phoenixes in the first week. This would add variety to development. They used to ban butterflies back then, among other reasons, because of long battles on the SOD timer, but now we have a chess timer. So I suggest discussing unbanning them as well.

In general, the fewer bans, the better. In the "competing" version — HotA — there are almost no bans left already.)
