You and almost everyone else who played ME2 the first time. The only real complaint people had about the combat system is that they missed the infinite ammo/weapon cooling feature from ME1. But you get used to it.
Pretty much how I felt when I started the game, TC. I took my time with the game too (probably played it over the course of about a month, did every quest and DLC) and towards the end I got a bit tired of the combat to be honest. Gets a bit repetative but the dialogue and encounters are always awesome.
on to ME3 next, but gonna take a break from this series after playing ME1 and ME2 back to back.
But, they should have kept the proper loot system from ME1 with some tools to manage the inventory
Moving to ammo is annoying and weird.
And I missed the Mako (I know I'm a lone voice here).
Most importantly though - nothing you do in ME2 really matters for the story. The entire thing is a side-mission from the big fight. ME1 ends with "the Reapers are on the way" and (spoilers) ME2 ends exactly the same way.
Legion and Grunt alone were worth the price of admission, though.

Hm, I like the ammo clip system, on Insanity it really added another gameplay element. You have to know where the clips are on the map, and manage how much ammo you use. In ME 3 they kept the ammo but it's dumped all over the map, sort of lost its strategy.
I miss the mako, but I feel having done the planet explorations in ME 1, I don't need to repeat that.
ME 2 seemed very much about the story. We find out what the reaper harvest really is, and what is done with the harvested species. Both ME 1 and ME 2 are about Shepard stopping the harvest on human colonies. The harvest takes centuries, apparently.
