You can still tele baal runs its not so bad if you have 50%dr and max resist in hell or nightmare. Ive been ambushed so many times with a 10sec lag which scares me a heap. For that 10sec lag i Thank my MERC for taking all the hits.

Tips are don't not trust any char coz pretty much any char can pk and i have seen it all. Mostly necros, amazons and sorc pk.
You can bot in hc even in hell mode only going for meph and pindy. But more better if you dont coz i dont =)....ive tried but doesnt work for me at all with my slow pc and connection.

HC is really fun but yea does get frustrating when you die at high levels.....my theory is make about 4-6 chars at high levels and have at least 3 of every items you got and dying would pretty much mean nothing to you.

Most HC players that i know who are rather godly just make a sorc for botting and focus all their wealth on 1 main char.
