I haven't tackled TDS or TBM since the changes but I have been working through CotF and things have definitely gotten easier. Aside from the Cooper HA's everything has been reasonable, for some reason those ones are harder. Since TDS and TBM are capped at 105 now you will have an advantage you wouldn't have had before. To be fair, the new mob templates hit harder and have more hp than the old ones, but since they are scaled lower that mitigates most of that. I'll be moving on to those expansions next and don't expect to be able to molo all the way through them yet, but should be able to beat some of them. That's at 108 in a mix of group gear with mostly EoK T1 and some T2 and RoS TS pieces. Will probably go all the way to 110 before I attempt the harder missions though.
