I'm looking at the Pathfinder rules for grappling, with the intent to use them instead of the usual D&D 3.X rules in future campaigns.
A flowchart on the unofficial prd page about combat tells me the controlling grappler can release the grapple at any time.
The second round flowchart tells me the non-controller might then try to gain control of the grapple or might try to escape it. Both take up the same action, both require the same checks.
Is there any reason a player who wants to escape should try to escape the grapple instead of controlling the grapple, then letting it go?
As far as I can parse the rules, trying to escape has the controller get a +5 to its rolls, while trying to gain control of the grapple does not, which makes it an easier check and has the same results.
Is this a bug, or is my logic (or the flowchart) wrong?
