I'll agree that a massive amount (order of magnitude ~10) of dedicated gunning Spiders can hold off multiple rush Leviathans - even fully equipped ones with AD and all - pretty well. That said, not many teams grow large enough to dedicate that number of players to defense in that manner. OTOH, if you had say just one or two gunning Spiders, one or two rush Leviathans with PD and AD and item spammage could take the Spiders out in relatively short order. Rockets are really fast, really powerful, and relatively long lasting (long lasting as compared to the rockets on say a Lancaster) on Leviathans. Even using three Repels against one Leviathan won't drain it completely of one Rocket. And most Leviathans have >1 Rocket. This is not even to say 'multiple Leviathans' or 'Leviathans with AD'. You've gotta be kidding about Terriers. They have comparatively horrible energy, and really horrible recharge. And their Bursts aren't "super sized" at all. Leviathan Bursts are weak, but with 3500 energy per shot (with ZPM), with their powerful Rockets, with their high bomb speed, with PD, with AD, with 3 Repels, and with Energy Infusion, Leviathans don't need strong Bursts to do damage. Items are limited so any strategy relying on items in order to survive does not imply the ability to "never get hurt." Because you'll run out sooner or later. As for your Spider, Mat, I'm sure you actually can survive indefinitely, if only because you could ?tw away whenever you got low on energy and needed to recover.
