Okay, let me clarify some things about modselection.
First: You are never forced to play a match with at least 1 mod. The mappool is designed in a size, that every match can be completely played without the useage of ANY mod.
Also, keep in mind, that not every team is capable of playing every mod. But yet, every team can select a mod only ONCE. This means, that if Team A is good at HD, they can use this advantage only ONCE in the entire match. If they have luck and can also win on HR, they can pick it. But if they are unfortune, the opponent is good at HR and they suck, so it's the opponent's advantage. Also it's very rare that an entire team is good at a specific mod. Usually it's only 1 or 2 of them. And in most cases, the opponent can provide also a player that is doing on this mod good, as well. But the rest of BOTH teams could perform poor, so picking a mod, even if 1 of your team is excellent in it, can be the wrong choice.
If your own team is uncomfortable with mods, don't select them. Be aware that most mod-players can only play excellent WITH their mod, not WITHOUT. From my side, it's very hard for me to FC maps without HardRock, with HardRock it's easy-peasy. For OnosakiHito, it's the same with HD.
So also remember, that if the opponent is only good at mods, and sucks without it, you can still win if you simply pick the nomod picks (which are as difficult in their own shape).
This is strategy. Just because you can't play a certain mod, that doesnt mean that you autolose. It has been seen in the OWC, that most matches had very low mod-selection - and I expect even more on TWC.
Yet keeping mods out makes many of our current participants being unable to reveal their true strengthes (especially they perform way more bad without their favorite mod) - so it's excluding them (I didnt participate on last TWC because I simply can't play without HardRock, and same goes for the majority of the HR/HD players).
Sure this tournament is for you, for having fun. But this is also a World Cup, not a random multiplayer. We give out physical prizes, we stream it to a huge audience, this is the biggest thing happening in Taiko no Tatsujin.
If you want to play like you want, I can understand that. No one wants to exclude you. But sure the main target of this tournament is to please the highest of the highest ot match up and battle for the crown. This can be enjoyable and many people do so. But if you feel you don't fit into this, you have mistaken the purpose of a "World Cup" then.
Unlocking this.
Edit: And yes, I am sorry that the announcement came so late and unexpected. We actually discussed this a lot and came to the conclusion that this might be the best. Also the "system" behind it (as explained above) tries to aim for pleasing everyone. That's why we use it. It's not about raising the difficulty. It's about giving this thing a variety layeer.
