I actually found it to be great fun, but to be fair, by act 3 I'm packing a number of grenades. But Assassin Duelist Hawke is such an efficient killing machine that enemies don't last long.
This. The only beef I had with a four rogue team was that Tallis is mostly useless.
That's great to know, thanks guys, I'll not shy away from bringing Varric and Izzy with me in MOTA now.
