On SunCruel, wouldn't Liquid Ooze be better than Rain Dish?
this has been discussed elsewhere but i can't remember where, so i'll bring up the key points:
1) rain dish is strong. incredibly strong. tentacruel is a good rain check because of rain dish, and frankly rain dish alone. it can't hurt most rain teams outright barring burn trolling or toxic spam, but rain dish makes it incredibly difficult to kill (barring stab ground or electric but honestly if you can't see that coming from a mile away you need to practice more). having that anchor for rain is very powerful. tentacruel cannot take specs hydro pumps in rain repeatedly unless it has rain dish. it WILL get worn down.
2) the matchups that are actually affected by liquid ooze tend to be affected by it in no major capacity; ie where liquid ooze would take effect, it generally doesn't change the outcome of the matchup. it's also worth mentioning that, generally, taking hits to inflict liquid ooze damage becomes harder with no recovery from *cough rain dish cough*. if you're in sun (meaning no rain dish recovery), you're packing a sun-boosted hidden power fire, which means all the common users of draining moves are getting hit hard by you anyway.
- drain punchers: conkeldurr does not break through tentacruel easily. with a fighting resist and invested bulk, it needs several boosts to hurt you. either way, cruel is not a great solution to conk in the first place - it risks giving conk a guts boost and will usually take a while to kill it. they aren't great solutions to one another. as for the occasional bulky breloom running drain punch, cruel loses to it outright - with toxic orb you can't burn it or toxic it, so it gets free time to swat at you or set up. liquid ooze does not change that.
- leech seeders: ferrothorn is the big one, and tbh you aren't gonna have a fun time against this no matter what you do, unless you run substitute. if you don't have activated rain dish, you still die slowly to leech seed, it just means ferro dies slowly and annoyingly with you. ferro still has the edge cause it's setting up spikes on you (spinning repeatedly means you die even faster cause iron barbs be trollin), unless you have sunboosted hp fire in which case remind me why ferrothorn was a problem to begin with?
as for random giga drains, the real problem is that either 1) they're weak as shit cause they're coming from opposing bulky grasses, meaning that honestly one hit of liquid ooze does NOTHING compared to the rain dish recovery you could be getting, and 2) if they're strong and invested, often there will be other coverage moves to hurt tentacruel, and you'll regret not having rain dish recovery when you have to start taking those. take RP genesect for example - sure you can eat a boosted giga drain and troll it with liquid ooze, but it's gonna break out a thunderbolt on you and you're gonna be wishing you had rain dish to stay alive. same with volcarona or such.
in general, there is no reason for tentacruel to NOT run rain dish. even in weatherless, even in sand (protip: don't run cruel in sand, seriously just run starmie), you should always run rain dish, never liquid ooze. it's not that liquid ooze is useless, but in general, you stand to gain a lot more from rain dish.
