Maybe this is too "basic" but I am really lost in this game. The thing is, I am from a country where ice hockey is almost non-existent. I regularly watch KHL and occasionally NHL but as you may guess, I am totally ZERO when it comes to tactics. I just know the basics like what lines do, how many players you have, which position does what etc...
I'm fond of football so I regularly play FM as well, where I can be successful since I know my way around. In EHM, it's really difficult. I am doing something but I feel as though I have literally %0 effect on team.
Is there any detailed explanation of tactics for dummies? I am not asking for a game guide or pre-set winning tactics... I just want to learn things and be competent to work around by myself.
Line changes are just too fast. For example, I am trailing by 2 goals... What am I to do? Players don't seem to be mattering much because as I said, they change every 30 seconds. Formation change is also out of option, as the scheme should always be like D-D-RW-C-LW. The players come in and go out, goals are scored and conceded and I am just like, "LOL what do I do now?"

I don't regret having bought the game at all - even if I can't do anything, I am glad to have contributed to this beautiful game. But I still wish I could be able to play it properly. Any kind of help, from guides to simple steps, would be appreciated.
