Practically their timing affects the Phase not the Steps. IE you can't use a REMDriver deployed during the Main Deployment Step to buff a REM deployed during the Reserve Step. But you can do it the other way around. But it's really irrelevant if you place the REMDriver on the table first and the REM second during the same deployment Step. At the end of placing all models you go "I'm deployed. This is a REMDriver with +1BS and it will buff that REM, which is a TR HMG bot." There is clear timing differences BETWEEN Steps; I'm arguing that enforcing timing WITHIN a Step is a *bad thing*. The alternative is that you're arguing I must always place the REM on the table before I place the REMDriver on the table. Or - in the case of Minelayer or Decoy - I must place the Trooper on the table first and then immediately follow it with the Marker the skill allows me to deploy.
