yes it is legal if you read the forum post at the top of the tavern page it gives you all the rules players with multiple characters must follow
what they are mearly doing is defending their mines with their mains and or using their mains clan members to help them take mines, both of which are legal

It has been a day and ihit has not respond yet, hopefully he is discussing it with the DE staff/support team and not just ignore it. Here is the rule: The main toon can not help his/her alt obtain any sort of benefits. Yes when a clan member use a bonecrushing sphere to help, that is legal but when the main decide to came and use the bonecrushing sphere than the main is helping obtain benefits for the alt not to mention when the main threatening to give someone a lethal curse if his/alt don't get that mine site.

thats a grey area its not illegal but its not right, but like it or not theirs nothing in the rules that directly say that a main cannot defend mines. the rules here are good but unfortunatly their are alot of ways to bend the rules without actually breaking them and this is one of thoes matters where the rules are being bent but not technically broken.

Fire3D,

Unless Ihit clarifies the situation the rules as Bones420 says state that you cannot enter the same fight as one of your alts under any circumstance - there is quite a bit of correspondence about what this means in the forum post but it is fairly straightforward once you realise there are no exceptions - so if the alt is involved in defending a mine then it is against the rules for the main or other alt to enter the fight but if the mine is not defended by the alt there is currently nothing in the rules to stop a main entering the fight and certainly nothing to prevent third parties defending a mine. One more point Ihit is aware of it as he mentioned it in another thread about barbarians and I am sure he would have taken the opportunity to point out it was a shackling offence but as he did not it probably explains your lack of response from him.

rhatmes,

I understand your point, not here to argue, just want ihit to clarify cause he is god of adan, his words are final. Let me explain my point of view, the hire miner is from an alt that means the alt owns the miner. When the main enters the fight with the miner, doesn't that means the main is entering the fight with the alt? Just something to ponder.

another grey area I have found is in sb... where many sadar send weak alts into it to boost the fight chances... if anyone who has experienced one of these fights you know what I speak of

Fire3D,
Your toons can never be in same fight. Period. Miner, BC, War, SB doesn't mater. Never put them in the same fight.

Zalex Jr,
we've reported those fights, and Ihit has confirmed, this is not happening. If you see a fight that you believe is with an alt in use, report it. ">

Exactly as Storm Kat says on every server someone likes to blame the alts in Sea Battles while 99 out of 100 times is just a inexperienced/undergeared/weak player and not an alt of another person.
