When I finally have a game like DA:O, I play it for the first time without any mods and wouldn't use, respectively buy item packs.
Perhaps I play it a second time with a completely different class, again without mods or purchased items.
For the next playthroughs I check the available mods, use mostly those for cosmetic matters. If item-DLCs are available, I buy them for a quicker
start, because - as we all know - some early chapters are a bit tedious at times. With a DLC-weapon / armour things are speeded up a bit.
But then, like in DA II, it spoils the fun. The DLC-weapons / armours are remarkably stronger than those which are available in the early chapters of the
vanilla version. Thus, the delight of finding better stuff respectively the feeling of having achieved something won't appear for a long time.
In ME they made a better job, IMO. The weapons from the DLC didn't feel overpowered, they were just different.
Summarized, most item-DLCs which contain equipment cut both ways:
Easing early (boring, tedious) routines on the one hand - spoiling the fun on the other.
