Great game ruined by difficulty issues

User Rating: 5 | Valkyria Chronicles II PSP

I'm surprised noone mentions the difficulty issues of this game. I was about 10 hours in and the game had been laughably easy but then in one mission all of a sudden BLAM an unbeatable boss. I looked for solutions online but even then I couldn't beat him unless I grind some I guess, meaning play the previous missions but I'm not going to do that because where is fun in that? Now I'm not sure if I want to get the original, the PS3 game. If it has the same issue then it deserved the low sales LOL

Same thing happened in Jeanne d'Arc but for some reason I wanted to keep playing although I was near smashing my PSP to a wall at least a few times.
