How often to farm mods?

*should

Same here. I think in the long run for me it is better to farm DT first. Shards are a safe thing and energy is spent efficiently. With mods one will definitely end up getting 20-30 useless pieces for every useful mod. To improve a toon substantially one needs 6 perfect mods. Why not save this frustrating effort for later?

Unless you need him for raids I would stick to mods, they are useful almost everywhere

I farm mods until I replace one or two items on my arena team. Then I farm a character to 7*.

I just repeat this cycle.

do both, mods and character shards.

Do shards in the week and mods in the weekend.

I am doing a little of both while farming DT. I spend 2 refreshes on farming mods, then a 3rd refresh and the rest of the the natural energy and bonus energy goes towards DT. While it's a slow process, I feel like I am progressing on both fronts.

I'm getting chirpa to 5* and then mods, just unlocked speed bonus mods so it will be a long grind to get 5x4 sets for my main toons, but it will pay off, and only getting chirpa to 5* because of the flash events, we will need him at 5* minimum soo, grind on!!!! ^_^

Some people have said they'll farm mods hardcore for 2-3 days, then someone's shards hardcore for 2-3 days. Rinse & Repeat.
