Your post reads as a fairly long winded whine, please don't do that.
One thing to note is that with the proposed changes we will only proc LnL off Black arrow and Immo traps periodic dmg and frost and freezing trap activation. The change that prevents bosses from triggering freezing trap means trap LnL procs will only come from adds.
Also in terms of managing cool down we now have to watch ES (6s), Black Arrow(30s), Aimed (8s), SrS(21s) assuming you glyph for aimed which I intend to. There is no rotation for SV possible anymore as 1 LnL will destroy the synergy with Black Arrow (BA). We will be pushing out even less steadies as a result so no one should glyph for steady and should instead glyph ES, Aimed, and KS.
I won't get into the PvP rap they did to us here but instead will have stuff posted in the PVP section soon. All in all I am slightly disappointed because the last thing we needed was to have our DPS become more complicated while we are already falling behind casters almost across the board.
