In 2v2 Riftbound, can you move your units to a battlefield controlled by your teammate?

Ruling: Based on the current comprehensive rules, moving to a teammate's battlefield would not trigger combat (since combat requires "opposing players"), but an older retired FAQ indicated teammates cannot have units at battlefields their teammate controls. This rule appears to have been omitted from version 1.1.

Nuances:

• The comprehensive rules use "opposing players" for combat triggers (rules 425, 426, 433, 322.7.a), which would technically allow moving to a teammate's battlefield without combat
• Rule 322.7 uses "controlled by a different player" which is inconsistent with other rules and appears to be an outlier/mistake
• Rule 462.8.c states control is not shared between teammates, but does not explicitly prohibit units at the same battlefield
• A retired FAQ document contained a rule preventing teammates from having units at battlefields their teammate controls, but this was not carried forward into version 1.1 of the comprehensive rules
