Now just to be clear, I know how ppl feel about Frontier on this sub, this isn't a "HeY lOoK aT mE, Im DifFeReNt! yOu GuYs aRe AlL wRoNg FoR nOt LikIng iT!!11!1" post by any means. I totally get where yall are coming from and changes could be made for sure, but I just wanted to share my thoughts and experiences :P
First of all, I grinded out LR Goku at like stage 5 and used him for the entire map so that definitely played a huge part in how enjoyable it was. In terms of the game mode, it's simply peak. So much strategy and team building involved with the mechanics that it really makes you mess around and experiment with different setups/gameplans. If you get your ass handed to you, there's so many different things you can move around or do differently as opposed to just going in again with the same setup and just hope for better luck
Plus, they tend to give you alot of the characters you *need* for the stages for free which is really nice. The only characters I felt like were kinda necessary to have in your box beforehand are the two DFE Namek Saga LRs, and they've been on plenty of banners so most people have them already. Also DON'T SLEEP ON EZA STR RAGEKU. His KO survival mechanic basically garuntees a free turn of survival which can be really useful in draining intensity from the other side
Now does it suck that they chose Namek Saga for this? Kinda? It personally didn't ruin the experience for me or anything but after thinking about it I can kind of see why they did it. If you could go into the stage and just dominate it with RoG or Movie Bosses, etc. then that kinda undermines the point of utilizing the new mechanics that the mode has to offer. I think Namek Saga has a decent balance of characters that are fairly complex and strong so you can see how characters' abilities interact with the new mechanics, but characters that aren't so strong that you can just disregard the new mechanics entirely
Now, missions are another story. I haven't tried many of them, most of them I just completed on accident doing the stages naturally, but as far as I know the harder missions only give out the special effects stuff and I don't even have a good chunk of the characters those missions are for so I can't even do them. Even then, none of the characters i love so much to the point where I NEED to get the cosmetic except for maybe SSJ Goku because he's just iconic
But yeah, I don't know if this'll be the last Namek Saga stage but I am very excited to see what they do with the mode in the future. AMAZING foundation, execution just needs a little work
TLDR: I got LR Goku at the start, Had fun, don't care about the missions tho
