Statesman,
Please don't adjust the Hollows. The zone is JUST fine teh way it is. Even the occasional large trains pulled to eth zone entrance is not overly bothersome (if you need to go afk, please leave...or adn take helaing aura off auto-activete eh folks).
I likely roll more new characters than anyone who plays. While there is great difficulty soloing in the Hollows at lvl 5-7 with most AT's, its not impossible, and certainly not MUCH harder than trying to do the 'Kill 10 COT in PP" at lvl 7.
That being said, I have run all AT"s, with most power sets in The Hollows, and a 5-8 member lvl 5 group can do quite well, and even lvl rather rapidly if you all watch each others backs and know your yous and your groups limitations. Obviously with strangers it is likely you will have a few trips to the Hospital under your belt before you learn how everbody in the group works. Also, new people to teh game (and more to the point this TYPE of game) will also have a harder time, especially with bosses.
If your new, or just want a tip, here is mine:
make sure your low lvl group has at LEAST one guy who can heal, 2-3 folks with a heal ability is better, but 1-2 is usually fine. For Noobies I VERY MUCH reccomend taht you get at east 2 people with a HOLD or STUN ability (that is make sure they match, 2 holds, 2 stuns..not one guy with stun, one with hold) and have the 2 coordinate to hit teh BOSS or LT at the same time. A single stun or hold is unlikly to shut down a boss at thsi lvl, and some LT's are tuff to stop as well, but being hit by the same powereffect form 2 sources stacks and will shut him down...length of time he is stopped is another matter. The type of tank or scrapper you take is nto REAL important, at this lvl they all work well, but I personally find that Super reflex scrapper lasts longer (HP-wise) but runs out of END faster. My opinion on blasters is not relevent today. I have been in a melee frame of mind for a month now, haveing done blasters to death the last few months.
Lastly, healing powers aside.....always try and find a defender with Force field, esp if he takes manuevers at lvl 6. If you do nto fight too far over your head you may not even need a healer, and should lvl VERY fast.
The last group I was in, on virtue (I usually play on VOctory) had the following guys types
Defender with FF and manuevers, lvl6
Defender with EMpathy lvl 6
Tanker Fire/Fire, lvl 5
Tanker Fire/Fire, lvl 6
COntroller Stone/empathy(?) lvl 5 or 6
and a pair of elec/?? blasters lvl 5 (these guys were brotehrs, and seemed to knwo the tanks)
This was our main group, and I am pretty sure (forgotto time it) but we were all lvl 8 when we finished, which was in less tahn 3 hours.....only lead shockers and the doors missions gave us any real problem....well except for that triple group pull we had...a few time hehe..sorry guys.
anyway, the zone is fine, teh developers rock, now I am off to make another idea toon trying out storm summoning.
See ya,
Dr. P
