Yeah, I would say that it's either a tactics change or boost the Gossamer Noble to have the tactics make sense.
(My preference would have been to boost the Gossamer Noble to keep the same tactics, but I do realize I'm in the minority for that one... so probably a tactics change.)
Yes, I'd definitely prefer to change the Gammaroid's tactics against Noble Gossamers.
In game mechanical terms the Gammaroid's stated anti-Gossamer tactics have a couple of problems in both AD&D or 3E.
The Noble Gossamers have hundreds of tentacles. The Gammaroid can only target three of them per round with its claw/claw/bite routine, so it'll get fatally stung way before it can remove all the Gammaroid's tentacles. That's ignoring the fact that the AD&D version of the Gossamer gives no rules for targeting the tentacles, which have neither an Armor Class or individual hit points listed.
Even if we assume that the Gammaroid only has to sever twenty tentacles (the number of sting attacks it can make) rather than the hundreds the Gossamer has available, that'll still take the Gammaroid seven rounds - by which time it'll almost certainly have been paralyzed.
However, all is not lost. The Gammaroid entry says they use their "whirling attack" against Noble Gossamers, so if we modify the 3E tentacle rules a bit so the Gossamer's tentacles are vulnerable to area attacks as well as Sunder attacks we could have the Gammaroid burn off the Gossamer's tentacles with the fire damage from its Flame Sheath.
