I kinda want to get this mentality out that having a single Riptide is “OP”. It’s not. They’re the Tau’s TEQ. It’s fair if they can have one if you bring some Termies or a Land Raider. If they bring multiple and in the Wing, then yes that is pretty cheesy. 

Also Kroot are shit. They’re just expendable meatshields. Having a whole army oriented around them would be incredibly boring. If Tau auxiliaries had the same love that Genestealers then that would be fine. 

A “fun” army to play against is something that tries to bring all the neat units into the battle in a combined arms fashion. Not just spamming any one single unit. A good Tau player would know that some well supported fire warrior unit is a cheaper and arguably better source of anti infantry fire power than the other units. 

I’m so tired of hearing non Tau players complain about “muh Battlesuits or muh Riptides” They’re there in the codex, they have a purpose, just like the FWs.source then any of the battle suits. Just because you get butthurt at the cheesemongers doesn’t mean that the other Tau players have to stop using a particular unit. Quit bitching.
