Respawn Zones for Slayer - Good or Bad?

I’m trying myself with building some gametypes that tone down Infinity Slayer-style play to a bit less hectic level as well as try to edit all the stock maps to compliment the gametypes better.

I’m currently working off of Complex right now, and would like to know what some others think about the use of respawn zones on certain maps. Which do you guys think would benefit from these, and which should be removed? Keep them all? I’m not too sure what the common opinion is on them.

This applies to Slayer at the moment.
