Is my tactic considered as suicide?

My formation is 2-1-4-3, (two DCs, one DMC, two AMCs along with ML and MR, and one ST along with AML and AMR).
I set the tactics to be full on hard attacking, mixed area focus, long range passing style, and forced counter attacks.
I also set the defensive tactic to be low, soft tackle, zonal marking style, and offside trap activated.
Making it to be a glasscannon team.

Just wanna know, is neglecting the defense for a total offense considered as a bad idea? I wanna make a team that will score so much that the enemy team wouldn't be able to catch up. If there's a better tactic for it, pls share it so i can have a better understanding of the game's system.
