Hello guys, Again I was wondering....What turrets for m1, m2, and m3 i should save up for. I have now realized I am pretty decent with firebird, rail and thunder. Also i was wondering if I should go for an isida instead. Firstly, I dont buy crystals and I mostly play only on weekends. So which would be a better option for me for my m1, m2, and m3/m4 turrets. Thank you in advance!

With the new update of Micro- upgrades, I was wondering if it was better to micro-upgrade my equipment or simply save up crystals for the next level? Help is greatly appreciated, thank you to all in advance!
