Just isn't true... I completed the entire quest without invading once. You only have to play in contested territory twice at the highest delta, but it doesn't say GM. You could probably turn down the difficulty to circumvent it. I plan on testing this in a min. (Turns out quest didn't update on my other 2 characters past 11). AND for clarity... Step 11 of the quest reads, [i]"Work your way up Syndicate Ranks by completing a priority contract for your syndicate. You may [u][b]OPTIONALLY[/b][/u] complete an invasion on the Lawless Frontier to disrupt Rival Syndicates. Wager additional deathmarks to increase rewards from successful invasions".[/i] Those are the facts. Invasions are NEVER forced or required. At most, you need to play in contested territory twice. 😇👍💠
