Speaking as a fellow Bronze player, and as a Support main for 4 seasons, when you and your Marksman decide to start roaming, make sure you not only have a
(if you insist on building it), but also some kind of early defense increasing item, such as a
or
, with the idea being that extra HP alone will only get you so far. This is primarily a recommendation since chances are, other lanes may not have had as easy a time as you did, and some opponents may have a bit more under their belt as a result. Whether it's a 3/2/2
, a 0/2/1
, or a 6/0/0
, all of them can be incredibly scary to a squishier group like you and your Marksmen, so having some survivability is key.
Now that we have this down, focus your Marksman on roaming where the enemy bot lane does, since they will want to try and capitalize on your weaker teammates to get caught up. Especially if they have an Assassin running in the middle lane, since it's almost a sure thing that he will roam to the weak lane too. Early detection and mitigation solves the largest part of the problem here. Additionally, if your team is a bit behind in kills, gold, etc., don't force the teamfights. I cannot stress this enough. Repeated early teamfights when you are behind seems like a good idea (kills means gold means evening out), but more often than not, being behind to begin with means that it's easy to lose further ground in poorly chosen fights, making it even harder to start mounting a comeback.
Lastly, consistent ultimates as
, even without a
, is possible if you wait for the enemy's opening disrupt and poke to be expended. If you are running it, SAVE
. In fact,
+
and a Black Shield on yourself all but guarantees you'll pull off a full ultimate even without a
(
could still work, but
is better for the flat damage absorption and immunity to
's effects in that absorption). Rushing a
might also be a nice idea, so you can abuse the movement speed bonus and active to keep up with people who try and flee the tether (since it does have a short range).
could be an option too, although
or
generally will prove a bit more useful thanks to their great passives.
Of course, this all applies to Bronze and Silver level play. Some of these tactics will not be as effective once out of Bronze and Silver (as some of my Diamond friends routinely showcase to me :P ), but it is a good catch all to start some experimentation.
I hope this helps a bit. I started practicing Top and Jungle this season (and last season), so I may be a bit rusty as a Support, but I still play it often enough. ;]
