It's not that the Krogan Soldier is unable to play or even solo on Gold... ALL classes are capable of a solid performance on Gold in the right hands. Heck, I just played through Gold yesterday with just me and a friend playing Krogan for a 2-man version of the Krogan Gold Challenge.
However, when (intelligent) people talk about tiers, they're not talking about whether it can be done, but what does it better, faster, et cetera. Sadly, I'm pretty sure the Krogan simply isn't one of the optimal choices.
Good play, though! You play the Krogan Soldier very similarly to how I use it, save that I use a Geth Plasma Shotgun (because I have it at X whereas the packs don't seem to want to give me a Graal

). It's a fun class, but it's a shame that melee and rage are so seldomly useful.
