Clans are usually more organized than groups of friends. In every game like D2, I always divvied up the clan members into specific 'squads'.
First Squad:
Primary assault
The First Squad usually did most of the damage, a decently sized group of tank players, accompanied by a ranged fighter/support unit.
Second Squad:
Crippling force
The Second Squad always went in with mages and healers to help strengthen the First Squad, aswell as slow, poison or harass the enemies we're facing.
Third Squad:
Two devoted healers, accompanied by four of my best, a summoner, a tank+dps, a healer/curser, a basic guard, aswell as myself.
In D2, during Clan Wars, we usually have to split our forces up into different groups.
Most of the Clan Wars consisted of "you die, you leave." terms before the war began.
A long while ago, I was a great tank/poison caster Necromancer. My strategy always consisted of:
Create a Bone Wall fortification around our Clan Members
Summon a Fire Golem and get my spells ready
Make sure I had 3/4 of my Belt filled with Mana Potions
Make sure I had 1/4 of my Belt filled with Rejuv Potions
No matter what type of character we faught, we almost never lost.
Paladins:
Even the fastest of them turn their attacks into an instant Kamikaze.
Have the best Bone mages cast 5-10 Bone Spirits and Decrypify/Bone Prison
Barbarians:
Many of them ran from the Bone Spirits, but using our faster running Necromancers we always forced them to run right into a wall using Bone Spears.
Amazons:
Bone Wall fortifications came in handy here, we all cast Bone Wall in the Amazons path and then mass Bone Spirit.
Sorceress:
We always wore Speed Sets, aswell as our Skill + Weapons & Jewelry.
Run from Sorc spells and then mass Bone Spear
Druid:
Read above.
Assassin:
If they try to sneak upto us, we simply use Poison Nova and encase ourselves in Bone Walls, massing Nova and Bone Spirit.
Personally, I managed to take out a few Paladins with melee, which seemed like quite a feat. For a Necromancer.
