With Ion Tokens stacking, the AT-ST would get no actions if it is getting hit by 2+ Ions each turn. Obviously those Rebels make themselves big targets, but each turn the AT-ST is locked down is one less turn it has a chance to "make back" it's points. Any resources used to eliminate the Ion troopers is resources not used to take out something more important, like a Commander. Plus in your example, that's over half the army points tied up with significantly cheaper units, leaving a large amount of point on the Rebel side free to accomplish objectives.
To be able to keep the AT-ST locked down the units with ion would have to take the ready action then the attack action. They don't have any available actions after that thus they are locked down.
