IsHealAssistantOfIndex() and IsRangedDpsAssistantOfIndex() are supposed
to iterate through the group and first return members with the
applicable role that have the assistant flag, and then iterate through
non-assistants only if there are not enough assistants for the
designated index. They are not written properly and actually completely
ignore the assistant flag.
I rely on these functions for significant roles in SSC and TK (which I
have decided I'll PR in the same way as SSC, as a long-term draft). I
have them fixed on my own fork, but it is problematic for testers if
these functions do not work.
So I've done three things here:
1. Fixed the functions to prefer members with the assistant flag.
2. Added a third parameter for ignoreDeadPlayers, like
IsAssistTankOfIndex() has. Note that the parameter is by default false
for IsAssistTankOfIndex(), meaning dead players are _not_ ignored. This
is not my preferred design choice--I think the default should be to
ignore dead players, but I have not changed the default and have made
the default the same for IsAssistHealOfIndex() and
IsAssistRangedDpsOfIndex(), since I don't know the intent of the
pre-existing boss strats that use the functions.
3. Changed the names to IsAssistHealOfIndex() and
IsAssistRangedDpsOfIndex() so they parallel IsAssistTankOfIndex(), and
made corresponding changes in the few boss strats that use the
functions.
Also, note that the functions _do _not_ exclude real players. I think
there are arguments for and against excluding real players. A fourth
parameter for this could be useful, but I've not made any change in that
regard.
