The only one i see that is of any worth is:
(!empty($user->lang['QUOTE'])) ? $user->lang['QUOTE'] : ucwords(strtolower(str_replace('_', ' ', 'QUOTE'))):
as a scout its hard to rasie focus to max. focus is needed to get that evac off.
best way to rasie it is to attack a gray or low green mob and then yell it off and exit combat so you get full regen. do this with 2 or 3 mobs.
then just stand there trying to summon that shroom pets from split paw or your call home spell. if using the call take a step before you finish the spell.
I don't have a scout to try the above trick on, so i can't really form an opinion. But if the Focus skill levels up quick enough i think it would be pretty good.
All others are as explained by Nearlight. Tip 4 is just common knowledge and anyone running up any steep incline would get the idea of knocking the enemy off the edge.
