personal insults aside
tactician difficulty is meant to be the hardest difficulty aside from honour (which is the same difficulty but with the added challenge of only having one save)
if you find it difficult just play on a lower difficulty. a lot of people will talk about how easy tactician is, but those are experienced players, and overall the game is still very hard
the game takes a while to get the hang of and there's no shame in playing on classic or explorer difficulty if tactician is making the game more hard than fun. the amount of fun you have is all that matters in the end
