"uniqueness" does not automatically make something interesting, let alone something players will like
that's not how game design works
In a lot of cases you are wrong. The battlefield series (Bad company 1 through Battlefield 4) has Bullet drop and travel time. When competing with COD, this a feature that a lot of people at first thought would not be very fun to have. But it was unique to battlefield and the fan base appreciates the fact that this is one of the features that really separates Battlefield from COD, and after playing Battlefield these players love the travel time and drop, since it makes sniper kills and long ranged kills, that much more satisfying
The same can be applied to the Airsoft thing here. Sure Walking back to deployment as a respawn may not sound satisfying, but its a unique characteristic that could be well accepted because its not the same run-gun- and respawn aspect that almost all TDMs on Blockland have. Even though you may not like the idea, doesn't mean that everyone else will not like it either.
Give it an honest shot.
